>> The war of words between President Donald Trump and Republican Senator Bob Corker escalating Monday with a warning of real war. In an interview with The New York Times, Corker saying, Trump is treating his office like a reality show, with reckless threats toward other countries that could set the US, quote, on the path to World War III.
Corker adding, he concerns me. He would have to concern anyone who cares about our nation. The interview coming after a Sunday tweet storm in which Trump lashed out at the Tennessee senator, a former ally who last week offered these troubling words about the White House state of affairs.
>> I think Secretary Tillerson, Secretary Mattis, and Chief of Staff Kelly are those people that help separate our country from chaos.>> After those remarks, Corker, who recently announced he will not seek re-election in 2018, found himself on the receiving end of a Trump Twitter attack. Bob Corker begged me to endorse him, I said no and he dropped out.
Trump also tweeting that Corker wanted to be his secretary of state but I said, no thanks. Then blaming the senator for the, quote, horrendous nuclear deal with Iran. Corker telling the Times, quote, I don't know why the president tweets out things that are not true. You know he does it, everyone knows he does it, but he does.
In August, Corker, who chairs the Senate Foreign Relations Committee, said Trump had failed to show the stability or competence to be successful. And his opposition to any tax reform initiative that increases the deficit has placed a major obstacle before one of Trump's top legislative priorities. Deputy US Politics editor Caren Bohan.
>> Bob Corker is a bad enemy for the president to make on many levels. He's a pivotal vote in Congress and he could block some of the president's initiatives on tax and other things. If the Mueller probe turns up findings that don't show the president in a good light, Corker could be one of the Republican voices criticizing the president and that could be problematic for him.
>> It wasn't always like this. Corker supported Trump in the 2016 election, and was briefly in the running for vice-president, seen as a possible bridge between Trump and the Republican establishment. Corker announced his retirement last month amid expectation he'd face a primary challenger from the far right wing of his party.
