South Carolina Sen. Lindsey Graham, who delivered a tearful Senate speech on John McCain, says he told President Trump that the president's handling of his friend's death "rips me off."
Graham revealed that he shared his anger with the president in an interview on the day of the first of three memorial services for the American hero.
He did not say when he warned the president, but revealed that he pressured his aides to return the US White House flag to half the staff on Monday.
"It leaves me senseless, and I let the president know," Graham told CBS in an interview.
"It moves me infinitely, and I let the president know," Graham told CBS.
Graham said he found Trump's answer. McCain, who spent decades in public service, captured the Republican Party's presidential nomination in 2008 and spent five years as a North Korean prisoner of war, "disturbing."
He said he did not call Trump to lower the White House flag to half the staff, but acknowledged that he pressured Trump's aides.
"No, but I called some people around," he said.
"I'm going to do everything I can to help President Trump, and when I'm wrong, I'll say it," Graham said. "It bothers me a lot when the president says things about John McCain."

Graham revealed that he called Trump's aides to complain that the White House flag was no longer half staffed.
Graham became entangled with Trump during the presidential campaign. The president launched the senator's famous cell phone during a campaign rally, and became Trump's confidant and golf partner.
But he also rejected the president on other issues during the interview, even with a blunt warning not to interfere with Mueller's investigation, which Trump calls a "witch hunt."
"The way he handled John's death is just, it was unsettling, we finally did it right … I'm not going to give up the idea of working with this president." The best way to honor John McCain is to help my country. .
Graham was McCain's friend for two decades
& # 39; Well, as long as I'm around, I'll remind you how this game sounds. I've been involved in Clinton's indictment. I understand the process quite well, "Graham said.
"Here, this is what I will tell the president. There is no scenario where you can finish this investigation, Mueller's investigation, through some political intrigue, and survive. That is your end. "
"The only person in the United States who can free Donald Trump is Mueller," Graham said.
John McCain and Lindsey Graham became friends in the early 2000s during the impeachment trial against then President Bill Clinton.
Graham delivered a tearful tribute to McCain in the Senate this week.
"For those who strive when they are young, remember John McCain, he missed a lot but never gave in. And the reason why we're talking about him today, and the reason why I'm crying, is because he succeeded despite his failures, "Graham said in the Senate plenary on Tuesday afternoon.
He added: & # 39; I do not cry for a perfect man. I cry for a man who had honor and was always willing to admit his imperfection. "
In his nearly 20 minutes of comments, Graham recalled McCain's fondness for bad jokes, his service to his country and how he believes "there's a little John McCain in all of us."
After his comments, Graham spoke with reporters about his friendship with McCain and conveyed the advice the late senator gave him on how to deal with President Donald Trump: "Help him when you can, just do not let yourself be absorbed by all this bull **** & # 39;
Graham added: & # 39; I said & # 39; Roger & # 39; So I'll help him wherever he can and they will not let me get caught up in the rest of the drama. "
