President Trump's trip to the G-20 conference echoed throughout the weekend, especially his first meeting with Russian President Vladimir Putin, but news of a controversial meeting his son took during the campaign broke Sunday evening.

While the G-20 dominated headlines for much of the weekend, Donald Trump Jr. became top news Sunday evening when he was put on the hot seat for taking a meeting with a Russian lawyer with connections to the Kremlin during the 2016 campaign.

While he originally said the meeting was to talk about the adoption of Russian children, the New York Times reported Sunday Donald Trump Jr. was reportedly promised compromising information on Hillary Clinton. Paul Manafort — Trump's then-campaign chairman — and Trump's son-in-law, Jared Kushner, were also in attendance, according to the report.

Trump Jr. confirmed the details of the meeting in a statement.

An informal adviser to the White House, Anthony Scaramucci, defended the oldest Trump son by calling him an honorable person who is the victim of a witch-hunt.

However, Democrats immediately jumped on the scandal and one, Rep. Eric Swalwell, of California, said it would be a "betrayal" unlike any other in politics.

That story distracted from the larger discussion about President Trump's foreign policy dealings in Hamburg, Germany at the G-20 conference, particularly his meeting with Putin.

During their meeting on Friday, Putin denied ordering an influence campaign on the American presidential election in 2016, Trump tweeted Sunday morning. Trump added that he wants to form an "impenetrable cyber security unit" with Russia in order to protect both countries from hacking.

That idea concerned Republican Sen. Marco Rubio, who said there was no chance of Putin ever actually working with the United States to protect American national security. He compared the deal to working with Bashar Assad to limit chemical weapons usage.

It didn't last long — by the evening Trump had backed off the idea.

Republican Sen. Lindsey Graham also slammed Trump for his attitude toward Putin in a fiery interview Sunday morning, saying Trump is "hurting his presidency by not embracing the fact that Putin's a bad guy."

Rep. Adam Schiff, D-Calif., said Trump wasn't dealing from a position of strength when he was talking with Putin.

Wikileaks trolled Trump in response to his tweet by suggesting founder Julian Assange be the one in charge of the U.S. partnership with Russia on cyber security.

Former U.S. attorney Preet Bhara sarcastically ripped Trump's statement about his meeting with Putin, comparing it to dropping a case against a murderer because the accused "vehemently denied" doing the crime.

Senate Minority Leader Chuck Schumer said Trump appeared to "acquiesce" to Putin's denial rather than pushing back on it. However, at least one report indicated Trump pressed Putin on the issue of election meddling at the very beginning of the meeting, which lasted about 40 minutes.

One topic that wasn't discussed was sanctions on Russia for their meddling in the election and in Ukraine. Trump tweeted action had to be taken in Syria and Ukraine before that discussion could take place.

Putin, for his part, said he believed Trump was satisfied with his denial of Russian meddling in the election.

The administration appeared to be confused on whether Trump accepted Putin's denial.

Treasury Secretary Steven Mnuchin said it didn't make sense for Trump to say publicly whether he had, in fact, accepted Putin's denial.

However, at about the same time, White House chief of staff Reince Priebus said Trump didn't believe Putin and accepted the intelligence community's ruling that Russia was behind an influence campaign on the election.

United Nations Ambassador Nikki Haley said, "everybody knows Russia meddled in our elections," despite Trump's reluctance to say so. She also defended Trump's decision to possibly partner with Putin on cyber security as an example of keeping your enemies close.

Putin and Trump appeared to have a good rapport with each other, with Putin jokingly asking if the journalists in the room during their meeting were "the ones hurting" him.

Trump ruffled some feathers by being the lone world leader to abstain from redoubling their country's commitment to the Paris Agreement on climate change. That decision led to the group being called the G-19 on Twitter, indicating the United States was abdicating its role as a world leader.

An Australian reporter gave a news report from the conference slamming Trump's decision to pull the United States back from its role as world leader. The video quickly went viral in American Sunday morning.

However, former House Speaker Newt Gingrich said Trump's choice is not a bad thing because Trump was fulfilling a promise to his voters that he was making the best deal for the United States, not for the world.

Gingrich wasn't the only political character from the past praising Trump. Former presidential candidate and Sen. Bob Dole praised Trump as restoring "strong American leadership" at the G-20 conference.

Trump did commit to some traditional U.S. allies, including teasing a "very powerful" trade deal with the United Kingdom and promised to take a visit to London soon.

He also met with Japanese Prime Minister Shinzo Abe to discuss North Korea following that country's missile test last week.

There was a minor embarrassment for the White House as it referred to China, and not Taiwan, as the "Republic of China." China is known as the People's Republic of China. Trump met with top Chinese leaders about North Korea while at the G-20.

At the end of the conference, Trump revealed the United States donated $50 million to a World Bank program that encourages women's entrepreneurship.

He also praised the safety of world leaders at the G-20, despite the protests outside the event by people he labeled "anarchists."

Trump and Putin also helped hammer out a ceasefire agreement in Syria that went into effect on Sunday. Trump tweeted the ceasefire could save many lives.

After the conference ended, Secretary of State Rex Tillerson said he doesn't think the United States and Russia will ever agree on whether the Kremlin ordered an influence campaign on the election.

However, Tillerson's cozy relationship with Putin was singled out by Arizona Sen. John McCain, who said he sometimes regrets voting for Tillerson as he passed through the Senate.

A few top Trump administration officials found themselves in hot water for political machinations.

Secretary of Health and Human Services Tom Price was accused of using campaign money to help with Senate nomination process, which is improper.

Vice President Mike Pence is also reportedly courting top donors at the Naval Observatory, his official taxpayer residence. His office denied that the four dinners held at the residence were fundraisers, which would be illegal.

First daughter Ivanka Trump found herself in the headlines again this weekend.

Her father said "it would be so much easier" for Ivanka if she were not his daughter, and she later took some heat for sitting in for her father at a meeting at the G-20 conference. Angela Merkel defended her appearance at the meeting as appropriate because she was a member of the American delegation.

Former Mexican President Vicente Fox poked at Trump for allowing Ivanka Trump to sit in on the meeting, saying the G-20 isn't "take your child to work" day.

Across the Pacific Ocean, North Korea's test of an intercontinental ballistic missile last week reverberated throughout the weekend as well.

The Air Force conducted an operation as a practice bombing run and the North Koreans deemed that exercise was a provocation.

Haley promised Trump would encourage China to do more to stop North Korea, even though he appeared to give up on that strategy in a series of tweets earlier this week.

Looking around the rest of the country, some lawmakers met with voters during the end of a weeklong recess from Washington.

Among them was Sen. Ted Cruz, who met a woman who apologized to him for being rude to him online.

Sen. Bernie Sanders went to West Virginia and Kentucky to rally against the GOP healthcare plan and encouraged voters to get their senators to pull away from repealing and replacing Obamacare and instead move toward Medicare-for-all.

Sen. Bill Cassidy, R-La., said the healthcare bill as proposed by Senate GOP leadership last month is dead. Cruz added the Affordable Care Act should just be repealed in total if the GOP can't reach a deal.

Back in Washington, Trump prodded Republicans to take the opportunity they have to repeal and replace Obamacare by reminding them of how long they're been promising to do so.

A report indicated Trump's advisers are working hard to kill a bill aimed at strengthening sanctions on Russia because it would tie his hands in negotiating with Putin.

In Colorado, hundreds of people withdrew their voter registrations in protest after the state submitted to a request from the Trump administration's request for information to investigate voter fraud.

Hawaii once again tried to limit the scope of Trump's travel ban a little more than a week after it went into effect. The state is fighting to get more people accepted into the state than the ban, as implemented, allows.
