Just before 10 a.m. Sunday, President Donald Trump attacked Republican Sen. Bob Corker on Twitter, and about an hour later, the Tennessee congressman fired back.

Trump said that Corker begged him for a re-election endorsement.

He also said Corker was “largely responsible for the horrendous Iran deal.”

Trump had previously encouraged Corker to run for re-election in 2018, The Associated Press reported.

Sources close to the situation also said that Trump’s Sunday morning tweets are all untrue.

Corker announced at the end of September that he wouldn’t seek re-election for his seat in Congress, in part because he wants to spend the next 15 months working independently as opposed to being bound by a re-election effort.

On Sunday, Corker’s office had no other response apart from his tweet.

Trump’s tweet storm could have been the result of a Corker mention on Fox News Sunday.

At about 9:45 a.m.—shortly before Trump tweeted—Fox’s Juan Williams and Chris Wallace were discussing the Iran deal and referenced comments Corker made recently that Gens. John Kelly and James Mattis, as well as Secretary of State Rex Tillerson, are the “people that help separate our country from chaos.”

Corker has batted down the idea that he will run for Tennessee governor, and some are now wondering whether he’s preparing for a presidential contest instead.

Iran deal
Trump is expected to “decertify” the international nuclear deal with Iran soon.

The 2015 agreement limits Iran’s ability to take steps toward the creation of nuclear weapons in return for eased economic sanctions.

Bloomberg Politics reported that Corker, who is head of the Foreign Relations Committee, is working on legislation to amend the agreement.

Corker spoke with The Washington Post about the need to renegotiate the deal but said that tearing up the agreement would cause a self-created crisis, that there’s a better time to do it and it should be with the goal of a strategic outcome.
