Trump's comments, which he made during an interview with ABC News, set off a political storm on Capitol Hill on Thursday, forcing Republicans to either break with Trump or remain silent amid a downpour of questions from reporters about accepting help from a foreign government.

He said he spoke to Trump on Thursday about the ABC News interview and reiterated that he should call the FBI if a foreign government tries to offer information on an opponent.

"Basically what I just told him is … you don't need to call the FBI cause somebody says they want to help your campaign, you need to call the FBI when somebody is trying to provide something of value to you that you think is inappropriate," Graham said.
 
He added that "when it goes down the road of 'I've got dirt on your opponent,' that's a bright line. The answer is no." 
 
Graham, who is up for reelection in a red state next year, was one of several Republicans who pushed back over Trump's claim that he would "look at" information about a political opponent even if it's offered by a foreign government. 
 
“I think you might want to listen. There’s nothing wrong with listening,” he told ABC. “It’s not an interference. They have information. I think I’d take it. If I thought there was something wrong, I’d go, maybe, to the FBI.”
 
 
“It would be totally inappropriate and it would strike at the heart of our democracy,” said Romney, an at-times vocal Trump critic who was the party's 2012 nominee for president.

"I mean, turn it over," Gardner added. 
 
 
Not every Republican was as ready to criticize Trump's remarks, though none have offered to back up his claims that candidates should accept information from a foreign government. 
 
 
"I’ve watched this president. I’ve listened to this president. He does not want foreign governments interfering in our election. He’s been very strong about that,” McCarthy said. “He’s been so strong against Russia.”

Some GOP senators also tried to flip the script by raising the 2016 election and the controversial opposition research dossier against Trump, known as the Steele dossier. Sources told The Washington Post in 2017 that Clinton's campaign and the Democratic National Committee (DNC) helped fund the research that was ultimately turned into the dossier. 

"I'm a little astonished at the outrage that I've heard because I didn't hear equal outrage when Hillary Clinton and the DNC paid a foreign spy to gather information from Russia," said Sen.

Grassley is one of several Republicans, along with Graham, who want to investigate the origins of the FBI's probe into the 2016 election and the Trump campaign.

But, Grassley added, the "bottom line is that whether you're a Republican campaign or a Democratic campaign you've got to be very protective of making sure that you don't do anything that enhances a goal of a foreign national or a foreign country."

"If I had knowledge that it was someone from a foreign country my first phone call would be to the FBI," Tillis said.

Asked if he had accepted information from a foreign government, he added, "absolutely not."
