Paul Ryan admits Republicans have to live with Trump's constant attacks

Paul Ryan signaled he has become resigned to the reality that President Donald Trump will use his Twitter account to attack other members of the Republican Party.

"It's what he does," Ryan told MSNBC's Kasie Hunt in a preview clip of an interview set to air on Sunday. "We've kind of learned to live with it," Ryan said.

Trump lately has targeted Sen. Bob Corker of Tennessee, the Republican lawmaker who has criticized Trump for publicly undermining his own secretary of state, Rex Tillerson. The president did not appreciate Corker's critique, later tweeting that Corker, who had already announced he would not seek reelection in 2018, had "begged" for his endorsement.

Corker responded, tweeting that it was a "shame the White House has become an adult day care center," and suggesting that someone had "missed their shift" that morning. In an interview with The New York Times, Corker said Trump's antics were putting the US "on the path to World War III."

Corker continued to admonish Trump on Friday,accusing the president of trying to "castrate" Tillerson.

Tillerson last week attempted to allay growing suspicions that a rift was developing between himself and the president after revelations had surfaced that he called Trump a "moron" during a meeting with national-security personnel.

Trump has previously attacked Ryan, Senate Majority Leader Mitch McConnell, John McCain, and many other members of his own party.
