WASHINGTON -- Donald Trump tried to assure skittish GOP lawmakers Thursday that they all share the same Republican Party goals, but his first appearance before the rank-and-file failed to soothe some deep concerns about his undisciplined campaign.
Protesters chanted in sweltering heat outside, while inside a packed room at the Republican National Committee, Trump offered a simple message, according to Rep. Ken Calvert of California: "We all need to stick together. Things will all work out in November."
With GOP lawmakers unanimous in their desire to beat Hillary Clinton this fall, some welcomed the reassurance and applauded Trump's remarks. It wasn't enough for others, as lawmakers who have been wary of Trump's incendiary comments and off-putting campaign style said they remain unconvinced.
"I said before the meeting that Donald Trump has a lot of work to persuade many Americans, including myself, that he is able to lead this great country," said Rep. Charlie Dent, R-Pa. "I still need to be persuaded."
Dent also said one House member "raised an issue about his comments about Hispanics generally, and how that was not helpful." Asked how Trump responded, Dent replied: "He said Hispanics love him."
Trump's appearance came on a circuslike day on Capitol Hill, with FBI Director James Comey testifying to a House committee about Clinton's email practices, summoned by Republican lawmakers furious about his decision, announced Tuesday, that Clinton should not face criminal charges.
Dozens of protesters awaited Trump, shouting slogans and waving signs that said Trump is "Dangerous, Divisive, Deceitful." Protesters chanted, "Donald Trump, he's a fraud. Sending our jobs far abroad." They held up large photos of GOP lawmakers, including vulnerable senators, wearing Trump campaign hats, as the billionaire arrived with daughter Ivanka and son-in-law Jared Kushner.
Rep. Adam Kinzinger of Illinois, an outspoken Trump critic, said there was a lack of energy in the room. "You could feel it," he said.
"I'm not a Never Trump guy, I've said I want to get there. I'm a Republican and I want to support the nominee," Kinzinger said after leaving the meeting early. "But things like the Saddam Hussein comment are not helping me get there," Kinzinger added.
He was referring to Trump having praised the late Iraqi dictator's terrorist-killing prowess. Trump defended himself over those comments Thursday, telling lawmakers it was an example of the media twisting his words, according to Rep. Kevin Cramer of North Dakota, a strong Trump supporter.
Cramer paraphrased what Trump said: "Here I was very critical of Saddam Hussein, saying he's a very, very bad guy, evil guy. And I wake up and I look at the media and they say I love Saddam Hussein."
House Speaker Paul Ryan said Trump sought to put the Saddam comment "into context, so people understood the context in which he was speaking about getting tough on terrorism."
Trump offered some what they wanted to hear. He talked of repealing President Barack Obama's health law, reducing regulatory burdens, overhauling tax laws and getting the Supreme Court to "be one that is more reflective of the values of the country," according to Rep. Tom Price, R-Ga.
Trump delivered a "great unifying speech," Price said, and his listeners were "very receptive."
In a tweet once the meetings were over, Trump said he had "great" and "interesting" meetings:
Ryan told reporters later, "We clearly have a presumptive nominee who wants to work with us on moving this agenda forward."
But others sounded unimpressed.
Rep. Mark Sanford of South Carolina called the meeting "a necessary check in the box." He said that his concerns about Trump are "tone and tenor."
"I like a lot of what he says, but not how he says it," Sanford said.
And speaking with Senate Republicans, Trump reportedly tussled with more than one of them--including Nebraska Sen. Ben Sasse, who has been publicly critical of Trump since he became the presumptive nominee. Sasse's spokesman went as far to call the election a "dumpster fire."
"Senator Sasse went to today's meeting ready to listen. Senator Sasse introduced himself to Mr. Trump and the two had a gracious exchange," the spokesman said after the meeting. "Mr. Sasse continues to believe that our country is in a bad place and, with these two candidates, this election remains a dumpster fire. Nothing has changed."
Sen. Jim Lankford of Oklahoma pushed back on reports of tension, saying the meeting was very productive overall and that they spent most of the time talking about policy. As for Trump's exchange with Sasse, Lankford said the two men were courteous in their disagreement.
Arizona Sen. Jeff Flake called the meeting "a bit tense" -- he had reportedly introduced himself to Trump as the other senator from Arizona--the one who didn't get captured, a reference to Trump's comments last year about Sen. John McCain. Trump had said then that he didn't think of McCain as a war hero because he had been captured.
"What an awful, awful thing to say about a war hero, to a war hero, and I don't think we can be dismissive of that kind of statement," Flake said. "You don't talk about someone who spent five years as a POW and could have come home earlier if he used his status because of who his father was -- but he stayed there. Then to be told that --have that just dismissed -- that's just wrong. And so I thought [Trump] needed to hear it from maybe the other senator from Arizona." McCain did not attend the meeting.
Flake criticized Trump on other fronts, too, mentioning his proposed Muslim entry ban, and his slurs against Mexican immigrants as murderers and rapists. "We can do better," Flake said. He conceded that he was glad that Trump seemed to be "walking back" his Muslim ban.
Then Flake brought up the judge in the Trump University lawsuits, whom Trump has implied might be biased against him because of his Mexican heritage. "I hope that he would apologize," Flake said.
"These are things the Republican nominee can't say, shouldn't say, shouldn't feel," he said.
Flake also brought up Trump's remarks on Saddam Hussein, too -- "he's killed terrorists--yeah, he's killed a lot of other people too. And I don't think we ought to be showing any admiration for Saddam Hussein," Flake said.
The gatherings came less than two weeks before the GOP's national convention, which a number of leading Republicans, including some in Congress, are skipping. A number of lawmakers also planned to skip Thursday's meetings. Sen. Kelly Ayotte of New Hampshire, in a tough re-election race, told reporters she had to attend a Senate Armed Services Committee hearing instead, while Florida Sen. Marco Rubio said he was scheduled to preside over the Senate.
It came on the heels of a fiery Trump speech Wednesday night in which he defended his retweet of the image of a six-pointed star alongside a picture of Clinton on a field of hundred-dollar bills. Many saw the symbol as a Star of David and considered the image to be anti-Semitic, and Ryan and others criticized the retweet. Instead of focusing on Clinton during his remarks Wednesday in Cincinnati, as Republican leaders would have liked, Trump mixed his attacks on the presumptive Democratic nominee with a defense of the tweet as well as earlier remarks complimenting Saddam. Trump argues the star in his tweet was a regular star that a sheriff might use.
The meetings come as two potential vice presidential picks -- Sens. Bob Corker of Tennessee and Joni Ernst of Iowa -- indicated that they weren't interested in running on the same ticket as Trump.
Democrats sough to capitalize on Trump's appearance on the Hill. The Democratic Congressional Campaign Committee released a pair of ads linking Republican lawmakers to Trump.
