But some Republicans left the meeting still feeling unsure about Donald Trump.
It wasn't enough for others.
Trump defended himself against some of his harshest Senate critics.
Finally, Trump took aim at Nebraska Sen. Flores quoted Trump as saying: "I'm going to make you proud". "I think the only time he's addressed the Republican Conference was when he called us to the White House to scold us".
Trump has said he agrees with the concept of opening ties but thinks that the US should have made a better deal. The most extensive word exchange was with Senator Jeff Flake from Arizona, who has publicly shown his concerns about the billionaire's candidacy.
Trump tried to be a blowhard and instead tripped on his own ego and lack of basic knowledge when he revealed that he didn't even know which of his party's Senators would be on the ballot with him this year. John McCain - who was a prisoner of war in Vietnam - was a war hero because he was captured. "But given some of the statements that have been made, I'm finding it hard", Flake said.
After the meeting, Flake allegedly told reporters, "I want to support the nominee".
It marks a notable shift for Trump, who said just weeks ago his former rivals who haven't endorsed him wouldn't be invited to speak at the convention.
Trump's meeting with House Republicans was less acrimonious, though he was questioned about his controversial remarks about Hispanics and other issues.
Asked if Trump could win his home state in November, Kirk said, "I don't think so". Eastern, privileged, wealthy bully.
Trump called Kirk, one of the more vulnerable GOP incumbents, a loser at the closed-door meeting with Senate Republicans on Capitol Hill on Thursday. In April, Duckworth's campaign launched an attack ad that criticized Kirk's support of Trump.
"It was a pretty relaxed meeting", Lankford said. He held a private meeting with Sen.
Rep. Peter King, R-N.Y., echoed Ryan's sentiment, telling ABC News it was an "extremely positive" meeting.
Guinta, the two-term representative in New Hampshire's 1 Congressional District, said in a statement to NH1 News that "House Republicans had the opportunity this morning to meet with Donald Trump to discuss the state of the Presidential election". "I still need to be persuaded". "You've been very critical of me", according to the Washington Post.
There were some reports of tension in Trump's meeting with Republican senators.
It wasn't known at press time what night Cruz would speak, whether it would be in prime time, and whether the two agreed to any restrictions on what he might say.
