Any call for Sen. Bob Corker to resign — like one made Monday by ex-White House adviser Steve Bannon — is "ridiculous," a Corker spokeswoman said Tuesday.

"It is ridiculous and does not merit a response," Corker's communications director, Micah Johnson, said in response to questions about Bannon's comments.

Earlier Tuesday, the White House would not weigh in on whether Corker should resign. But White House Press Secretary Sarah Huckabee Sanders blasted Corker for his role in the Iran nuclear deal, as the feud between the Tennessee Republican and President Donald Trump continued.

Sanders said it is up to Corker and the people of Tennessee to decide if the former Chattanooga mayor should resign. Bannon made his statement Monday night on Fox News.

Sanders picked up on an attack from Trump in tweets over the weekend, blaming Corker for passage of a controversial deal with Iran regarding the country's nuclear capacity.

"Sen. Corker worked with Nancy Pelosi and the Obama administration to pave the way for that legislation, and basically rolled out the red carpet for the Iran deal. Those are pretty factual," Sanders said.

However, Corker voted against the Iran nuclear deal, an agreement negotiated by the Obama administration. The legislation Corker authored created the framework for legislative oversight of the deal, as the senator wrote in a 2016 op-ed in the Washington Times.

"Our bill was the only way to guarantee a role for Congress. It forced the details of the agreement to be revealed, and while in the end there were not enough votes to stop the deal, it demonstrated that a broad bipartisan majority opposed implementation," Corker wrote at the time.

Trump is expected to announce this week his decision on whether to "decertify" the agreement.

The Trump-Corker feud, months in the making, really ignited Sunday morning after the president tweeted Corker "begged" for his endorsement and didn't have the "guts" to run for re-election.

Corker responded on Twitter, saying the White House had devolved into an "adult day care center."

A fellow Tennessee Republican, Rep. Diane Black, launched her own attack Tuesday in response to that Corker statement. In an interview with conservative radio talk show host Hugh Hewitt, Black — who is running for governor — said "I think the Senate is an adult day care center."

Corker, who announced his impending retirement from the Senate in late September, denies he asked for Trump's endorsement. His chief of staff told the USA TODAY NETWORK that Trump called Corker and tried to talk him into running, promising to campaign for Corker.

On Wednesday, Sanders said the president's statements are accurate.

She also responded to comments Corker made in a Sunday New York Times article, where he said Trump's threats could put the U.S. "on the path to World War III."

“Sen. Corker is certainly entitled to his own opinion, but he is not entitled to his own facts," Sanders said.

On Wednesday, Trump incorrectly tweeted "Liddle' Bob Corker" was "set up" by the Times when they recorded their interview. However, the Times released audio Wednesday of Corker saying he understood reporters were recording the interview.
