MATTIS ISIS UPDATE: In what will be only his second meeting with the news media in the Pentagon briefing room in his four months on the job, Defense Secretary Jim Mattis, along with Joint Chiefs Chairman Gen. Joseph Dunford, will outline progress in the fight against the Islamic State in Iraq and Syria. Pentagon officials say the 1 p.m. briefing will review what has been accomplished in recent months, but will not reveal the new strategy to defeat the terrorist group, which was ordered by President Trump shortly after he took office. “You're going to see some incredible numbers with respect to the success of General Mattis and others with the ISIS situation,” Trump said yesterday. “The numbers are staggering, how successful they've been — the military has been.” A Pentagon official yesterday confirmed Mattis would be delivering an upbeat assessment. “The fact is we are doing pretty well,” the official said.

SYRIA ATTACK: In Syria yesterday, the U.S. bombed a convoy of military vehicles that it said was encroaching on a deconfliction zone along Syria’s southern border with Iraq. The convoy was said to comprise pro-regime Shiite militia who were heading in the direction of Tanf, where U.S. special operations forces have been training local fighters to battle ISIS. The U.S. military said the Russians, who support the Bashar Assad regime, were called on a hotline in an attempt to warn the convoy off. Eventually, U.S. warplanes fired warning shots. When the show of force was ignored, the convoy was attacked from the air. Several vehicles were destroyed, and an undetermined number of fighters on the ground were killed.

During a Pentagon event with the Swedish defense minister, Mattis said the unusual attack on Syrian pro-government forces did not reflect any change in the U.S. policy to avoid direct involvement in Syria’s six-year long civil war. “We're not increasing our role in the Syrian civil war, but we will defend our troops, that is a coalition element made up of more than just U.S. troops,” Mattis said. “And so we'll defend ourselves if people take aggressive steps against us, and that's been a going-in policy of ours for a long time.”

TRUMP’S NEW TUNE: The president departs Joint Base Andrews this morning on his first foreign trip. Trump’s first stop: Saudi Arabia, a country he excoriated on the campaign trail and during presidential debates. Saudi Arabia, Trump said last June, is a country “where being gay is also punishable by death.” And he singled out the kingdom for not paying its fair share for its own defense. “Saudi Arabia, nothing but money. We protect Saudi Arabia. Why aren't they paying?” Trump said. And he accused the Saudi government of a “pay for play” scheme saying that 2010, in order to get approval from Hillary Clinton’s State Department to buy arms from the United States, the Saudis paid off her husband. “What did Saudi Arabia do? They paid Bill Clinton a fortune to do a speech. Later that year, Clinton's State Department signed off on arm deals between the United States and Saudi Arabia, shocking, shocking,” Trump said in an October campaign event.

But that’s all in the past. Saudi Arabia is literally rolling out the red carpet for the American president, who is seen as a breath of fresh air after Obama administration's cool relations with the longtime ally. American flags are flying over the streets of Riyadh, and the Saudi government has organized a dazzling array of events to coincide with Trump’s visit. And the president is not arriving empty handed either. He comes bearing an arms deal reportedly worth in excess of $100 billion and which the New York Times said was personally negotiated by his son-in-law Jared Kushner.

BREAKING: Prosecutors in Sweden are dropping rape charges against WikiLeaks founder Julian Assange, who has been holed up the Ecuadorean embassy in London for five years. In theory that means he would be free to leave the sanctuary of the embassy, but he may still fear extradition to the United States.

HAPPENING TODAY, IRANIAN ELECTIONS: Iranians are voting today to decide whether to give incumbent Hassan Rouhani a second term, or go with his hard-line challenger cleric Ebrahim Raisi. Two other minor candidates are also in the race. Rouhani, who negotiated the nuclear deal with world powers, is seen as a moderate willing to engage with the West, while Raisi is closer to Supreme Leader Ayatollah Ali Khamenei.

From the AP: “Rouhani, 68, is a moderate cleric elected in 2013 on pledges of greater personal freedoms and improved relations with the West. His government negotiated the 2015 nuclear deal, which saw Iran accept curbs on its nuclear program in exchange for relief from crippling international sanctions.

“Raisi, 56, is a hard-line cleric close to Khamenei who has vowed to combat poverty and corruption. He could pose the biggest challenge to Rouhani, especially if he can unify hard-liners.”

CHINA INTERCEPT: The U.S. military is reporting what it has termed an “unprofessional” intercept of a U.S. WC-135 plane flying in international airspace over the South China Sea Wednesday. One of the two Chinese Sukhoi Su-30 jets flew upside down over the U.S. plane, according to CNN. A U.S. military spokesman said the intercept was unprofessional because of “the maneuvers by the Chinese pilot, as well as the speeds and proximity of both aircraft,” adding that the incident was being addressed with China “through appropriate diplomatic and military channels.”

TWO CARRIERS OFF KOREA, REAGAN JOINS VINSON: The U.S. has dispatched a second aircraft carrier to waters off the Korean peninsula ostensibly to take part in training exercises. The USS Ronald Reagan has just departed Japan, and is now in the Western pacific, where the the USS Carl Vinson is already on station. Both ships are in the same general area but are “not in close proximity to each other,” according to one one official. “We don't discuss the future operations of our ships and aircraft,” said a spokesman in an statement last night. “As stated in the recent release, USS Ronald Reagan (CVN 76), and Carrier Air Wing (CVW) 5 just started their 2017 spring patrol [and] are currently focused on flight deck and carrier qualifications.” The deployment might be seen as preparation for a routine turnover with the Vinson strike group, were it not for the high level of tension with North Korea over its continued missile tests, and expected sixth nuclear test.

A REAL DENIAL DENIAL: Trump was unequivocal in his denial that he ever told the former FBI director to back off the investigation into a his former national security adviser. "In the light of a busy news week, people would like to get to the bottom of a couple things,” WJLA reporter Scott Thuman asked at yesterday’s news conference. “Did you at any time urge director James Comey in any way, shape or form to back down on the investigation into Michael Flynn?" Trump cut him off with a terse, "No, no. Next question.”

Trump also denied once again that there was any collusion with the Russians during the campaign. “Well, I respect the move, but the entire thing has been a witch hunt,” he said in reaction to the appointment of former FBI director Robert Mueller as special counsel to investigate the Russian connection. “There is no collusion between certainly myself and my campaign. But I can always speak for myself and the Russians — zero,” Trump said. “I think it divides the country. I think we have a very divided country because of that and many other things.”

The man who appointed Mueller, Deputy Attorney General Rod Rosenstein, briefed senators behind closed doors yesterday. Afterward, Sen. Lindsey Graham said he thought the independent investigation would limit what Congress can do. “It was a counterintelligence investigation before now, it seems to me now to be considered a criminal investigation,” Graham said. “I find it hard to subpoena records of somebody, like Mr. Flynn, who may be subject to a criminal investigation because he has a right not to incriminate himself. As to Mr. Comey, the former director of the FBI, coming before the committee. If I were Mr. Mueller I would jealously guard the witness pool.” Graham predicted no more hearings like the recent one featuring fired deputy AG Sally Yates, or former DNI James Clapper. “So one of the losers in this decision is the public,” Graham said.

In that private briefing, Rosenstein reportedly told senators that he knew Trump would fire Comey before he ever wrote the memo laying out the case against him. It was “clear as day,” Democratic Sen. Chris Murphy told MSNBC. “There's no question about it. It was in his opening statement. He laid out the narrative that ultimately led to the decision to fire Comey. Now, there are lots of holes in that narrative.” But Republican Sen. Marco Rubio didn’t hear it the same way. Asked, “Is it your understanding that Rosenstein knew that Comey was going to be fired before he wrote his memo?” Rubio answered “I'm not sure he addressed that with a level of clarity that most people wanted to hear.”

WILL IT BE JOE? Trump said yesterday that he is nearing a decision on who should replace Comey, telling a group of television anchors at the White House that former Sen. Joe Lieberman is his leading candidate. "We're very close to an FBI director," Trump said, adding that he would announce the new director "soon." Lieberman, former Connecticut senator and vice presidential candidate in 2000, was among a handful of candidates who met with Trump on Wednesday at the White House, according to press secretary Sean Spicer. Acting FBI Director Andrew McCabe also met with the president this week.

OUTRAGE OVER ERDOGAN: Sens. John McCain and Dianne Feinstein on Thursday blasted Turkey's president and urged him to punish his security staff for a bloody scuffle with protesters in Washington this week. "The violent response of your security detail to peaceful protesters is wholly unacceptable and, unfortunately, reflective of your government's treatment of the press, ethnic minority groups and political opponents," the two senators wrote in a letter to President Recep Tayyip Erdogan.

The clash outside a Turkish ambassador's residence Tuesday was caught on video and showed dark-suited Erdogan staff punching and kicking the protesters while being pushed back by police. Earlier on Thursday, McCain said he would "throw the Turkish ambassador out," during an appearance on MSNBC's "Morning Joe."

MILITARY HANDGUNS A CLICK AWAY? Republican Rep. Mac Thornberry wants to let the military do a whole lot more of its own shopping online to cut costly bureaucratic red tape. The Texas chairman of the Armed Services Committee unveiled new legislation Thursday that would allow it to buy everything from pens to treadmills from business-to-business sites such as Staples and Amazon, eliminating the current "expensive" and "onerous" contracting and scheduling process. But could it also work for firearms? “Maybe it's OK to get our handguns in a commercially available way in the future," Thornberry said.

An expert panel told his committee this week that military handguns are a prime example of the delays and waste of acquisition that the Republican chairman has been working to root out for the past two years. The Army spent 10 years and $15 million trying to put together a request to gunmakers for an M9 Beretta replacement. Meanwhile, U.S. small arms companies make more handguns in a month than the Army will buy in 25 years. But don’t expect to see any immediate legislative moves. "We take this step by step,” Thornberry said. This year, he’s focused on saving the Pentagon big on what he calls the less glamorous side of acquisition, such as office supplies and exercise equipment.

BRANSTAD ADVANCES: Senators voted 86-12 on Thursday to advance the nomination of Trump's pick for ambassador to China, setting up an expected confirmation vote next week. Iowa Gov. Terry Branstad is expected to be an important lieutenant to Secretary of State Rex Tillerson, who has had to travel to Beijing once already for talks related to the threat of North Korean nuclear weapons.

"I will work tirelessly to represent America and her citizens to the best of my ability," Branstad told the Senate Foreign Relations Committee during his confirmation hearing. "I will champion American interests in China with as much fervor and dedication as I have championed Iowa's interests during my more than 22 years as governor."
