IT’S SHOWTIME: President Trump says he thinks he’ll know within “the first minute” whether “something good is going to happen” in his historic meeting with North Korea’s Kim Jong Un. The two leaders are in Singapore in separate hotels, and are set to me meet Tuesday morning, which is tonight Washington time.

HAPPENING TODAY: The Senate is set to take a procedural vote this evening at 5:30 that could kick off floor debate on the 2019 National Defense Authorization Act. The must-pass $716 billion policy bill got held up last week after an objection by Sen. Pat Toomey. Over the past few days, Sen. Jim Inhofe and other senators have been working out a deal on what amendments could get a vote during the debate. But more delays could be possible if Sen. Rand Paul demands his amendment ending indefinite detention of terror suspects is included.

HOUSE SPENDING BILL MARKUP: Also this week the House Appropriations Committee is slated to mark up its annual defense spending bill. The hearing is set for noon on Wednesday. The bill includes $675 billion for the Defense Department and funds for 93 of Lockheed Martin’s F-35 joint strike fighters, which is 16 more than the 77 requested by the military. The House Appropriations defense subcommittee finished its markup of the funding bill last week without adding any amendments.

ALSO TODAY: The Defense Department is scheduled to conduct its 7th Annual LGBT Pride Month Celebration in the Pentagon’s Center Courtyard this morning, weather permitting. But you won’t see any mention of the 11:30 a.m. ceremony on the official DoD government website. The low-key event is getting lower-key every year, now that Trump has moved to ban service by transgender troops, and Defense Secretary Jim Mattis affirmed the decision in a February memo that concluded there was “substantial risk” in allowing the “retention of individuals with a history or diagnosis of gender dysphoria.”

Last year, Anthony Kurta, the Pentagon’s acting undersecretary of defense for personnel and readiness, issued a memo stating, “The struggles, sacrifices and successes among the LGBT community continue to shape our history and remind us to uphold tolerance and justice for all.”

There is no official proclamation from the Pentagon this year, but at the State Department, Pompeo issued a statement joining “people around the world in celebrating Lesbian, Gay, Bisexual, Transgender, and Intersex (LGBTI) Pride Month,” and reaffirming its “commitment to protecting and defending the human rights of all.”

MCCAIN RAPS TRUMP: Sen. John McCain said Friday that Trump is “inexplicably” showing deference to Russia and treating allies with contempt by proposing that Moscow have a seat at the Group of Seven summit of leading economies. Russian President Vladimir Putin caused his country to be ejected from the group due to his 2014 annexation of Crimea and occupation of Ukraine, which both continue today. McCain, who has been in Arizona since December battling an aggressive form of brain cancer, said in a statement.

“Nothing he has done since then has changed that most obvious fact. Every day, Russian-led separatist forces are killing Ukrainians in the Donbass. Every day, Putin’s forces are helping the Assad regime slaughter the Syrian people and every day, through assassinations, cyber-attacks, and malign influence, Russia is assaulting democratic institutions all over the world,” McCain said. “The President has inexplicably shown our adversaries the deference and esteem that should be reserved for our closest allies. Those nations that share our values and have sacrificed alongside us for decades are being treated with contempt.”

ONE SMALL STEP: The Taliban surprised some skeptics by indicating it will observe a temporary cease-fire announced last week by Afghan President Ashraf Ghani that is to coincide with Eid, the holiday that marks the end of Muslim holy month of Ramadan. In a statement to reporters, the group said it will honor a truce with Afghan forces for three days but would continue attacks on foreign troops.

The AP reports the Taliban attacked a checkpoint in the southern Kandahar province Saturday, killing five security forces.

At a meeting of NATO defense ministers Friday, Mattis said Ghani was able to make the “very bold statement” because the NATO mission has put him in a position of strength. “Afghans’ security forces continue to improve. All six Afghan corps are deployed throughout the country, demonstrating Afghan resolve, while the Afghan government pursues a stable and inclusive political order for its people, with NATO’s support,” Mattis said.

THE COLOMBIA MODEL: Both Mattis and NATO Secretary General Jens Stoltenberg have adopted the same talking point, that recent violence in Afghanistan is not a sign that things are going badly. Both point to Colombia, where in 2016 a negotiated agreement between the government and the Revolutionary Armed Forces of Colombia, or FARC guerrillas, ended a bloody 52-year war that killed an estimated 260,000 people.

“I recently met the president of Colombia, and he told me about the peace process there, where they actually were able to talk and fight at the same time,” Stoltenberg said Friday. “I think actually it is possible to also look to other peace processes where it has been possible to overcome years of conflict and then reach a negotiated peaceful solution.”

THE WAR IN SOMALIA: Most of the 500 U.S. troops working with local forces in Somalia are able to hang back, and assist the troops fighting al-Shabaab militants with intelligence and air support. But in combat, it’s not possible to stay out of the line of fire. On Friday, one U.S. special operations soldier was killed and four U.S. service members and one partner force member were wounded as the result of an enemy attack.

The Pentagon says Staff Sgt. Alexander Conrad, 26, of Chandler, Ariz., died from wounds sustained in “indirect fire.” Conrad was assigned to 1st Battalion, 3rd Special Forces Group, Fort Bragg, N.C.

LANCERS GROUNDED: The Air Force said Friday it ordered a grounding of its B-1B Lancer bomber fleet after a problem with an ejection seat. One of the long-range strike aircraft made an emergency landing in Midland, Texas, when the issue was discovered and the stand-down was ordered on Thursday, Air Force Global Strike Command announced.

The Air Force Safety Investigation Board is investigating the problem and the fleet will remain grounded until it is resolved, the command said. “The SIB’s purpose is to prevent future mishaps or losses and is comprised of experts who investigate the incident and recommend corrective actions. The safety of airmen is the command’s top priority,” according to the release.
