President Donald Trump and Sen. Bob Corker have been feuding for the past several weeks on foreign policy and tax reform.

Corker appeared on several TV networks Tuesday morning and criticized Trump, telling ABC that the president should leave tax reform "to the tax-writing committees."

Trump fired back on Twitter, writing that Corker "couldn't get elected dog catcher in Tennessee," the senator's home state.



President Donald Trump engaged in another feud Tuesday with Sen. Bob Corker, a Republican who has turned into one of the president's chief critics. The latest exchange came hours before the president was set to attend a GOP policy lunch on tax reform.

"Bob Corker, who helped President O give us the bad Iran Deal & couldn't get elected dog catcher in Tennessee, is now fighting Tax Cuts," Trump tweeted, apparently in response to an interview Corker participated in earlier Tuesday on "Good Morning America."

"Corker dropped out of the race in Tennesse when I refused to endorse him, and now is only negative on anything Trump. Look at his record!" he added.

The Tennessee Republican hit back on Twitter, writing: "Same untruths from an utterly untruthful president. #AlertTheDaycareStaff."

The president wrote on Twitter later Tuesday morning, "Isn't it sad that lightweight Senator Bob Corker, who couldn't get re-elected in the Great State of Tennessee, will now fight Tax Cuts plus!"

It was not the first time Trump had claimed that Corker, who is retiring from the Senate in 2018, chose not to run again only because the president wouldn't endorse him. Corker's office has explicitly denied Trump's statements.

In an interview with ABC's "Good Morning America" on Tuesday morning, Corker stood by earlier criticism of the Trump presidency. He has previously said the White House was an "adult day care center" and that Trump was pushing the US on a path toward "World War III."

Corker, the chairman of the Senate Committee on Foreign Relations, said Tuesday that on foreign policy Trump should "leave it to the professionals for a while."

He also advocated a hands-off approach from the president on tax reform.

"What I hope is going to happen is the president will leave this effort, if you will, to the tax-writing committees, let them do their work, and not begin taking things off the table that ought to be debated in these committees at the proper time," Corker said.

The senator has been vocal about his concerns that the Republican tax plan could balloon the federal deficit.

"Unless it reduces deficits — let me say that one more time — unless it reduces deficits and does not add to deficits with reasonable and responsible growth models, and unless we can make it permanent, I don't have any interest in it," Corker said at a recent Senate Budget Committee hearing.

Corker made the media rounds on Tuesday, appearing on NBC as well as CNN, where he said Trump would be most remembered for the "debasement of our nation."

Asked whether he regretted supporting Trump during the 2016 presidential election, Corker said: "Let's just put it this way, I would not do that again."

Corker has been vocal in his criticism of Trump since announcing his planned retirement, and the president has responded in kind.

"What we need to do is support him when he's right and check him when he's wrong," Corker said Tuesday, "which is plenty."

The feud was obviously on Trump's mind throughout Tuesday.

"Sen. Corker is the incompetent head of the Foreign Relations Committee, & look how poorly the U.S. has done. He doesn't have a clue as the entire World WAS laughing and taking advantage of us," Trump tweeted later Tuesday morning. "People like liddle' Bob Corker have set the U.S. way back. Now we move forward!"

As it dominated the news of the day, Corker responded to the president's messages, saying, "you would think he would aspire to be the president of the United States and act like the president of the United States."

"I've seen no evolution in an upward way," Corker said. "It appears to me that he's almost devolving."
