Republican U.S. presidential candidate Donald Trump greets Senator Bob Corker (R-TN) at a campaign rally in Raleigh, North Carolina, U.S., July 5, 2016.
"Strange statement by Bob Corker considering that he is constantly asking me whether or not he should run again in '18. Tennessee not happy!" Trump tweeted.
Trump's tweet comes a week after Corker offered some sharp criticism of the president at a town hall in Tennessee.
"The president has not yet been able to demonstrate the stability nor some of the competence that he needs to demonstrate in order to be successful," Corker said. "He also recently has not demonstrated that he understands the character of this nation. He has not demonstrated that he understands what has made this nation great and what it is today ... and without the things that I just mentioned happening, our nation is going to go through great peril."
When asked about Corker's comments at a press briefing on Thursday, White House press secretary Sarah Huckabee Sanders called the remarks "outrageous" and said they did not warrant a response.
"I think that's a ridiculous and outrageous claim and doesn't even require a response from this podium," Sanders said.
Trump's clashes with lawmakers in his own party have intensified in recent weeks. He has publicly feuded with Sens. Lindsay Graham, John McCain, and Jeff Flake, as well as Senate Majority Leader Mitch McConnell.
Over the course of his presidency, he has also publicly attacked Sens. Marco Rubio, Rand Paul, and Lisa Murkowski, among others.
