Donald Trump has got involved in another spat with one of his party's senators, this time over tax cuts.

The President went on the attack after senator Bob Corker, a Republican from Tennessee, said the White House should leave it to Congress to work out how to pay for Mr Trump's proposed $1trn (£761bn) tax cut.

Mr Trump took umbrage at the interview and fired off a tweet claiming Mr Corker "couldn't get elected dog catcher" in his home state:

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.... — Donald J. Trump (@realDonaldTrump) October 24, 2017

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! — Donald J. Trump (@realDonaldTrump) October 24, 2017

Mr Corker hit back through his own Twitter account, reprising one of his familiar lines of attack on the White House:

Same untruths from an utterly untruthful president. #AlertTheDaycareStaff — Senator Bob Corker (@SenBobCorker) October 24, 2017

Mr Corker, who serves as chairman of the Senate Foreign Relations Committee and will not stand for re-election in 2018, has previously labelled the Trump administration an "adult day care centre" and claimed the 45th President could be leading the US on a path to World War III.


As Mr Corker did the rounds on the US television networks, Mr Trump continued to attack him:

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..... — Donald J. Trump (@realDonaldTrump) October 24, 2017

...the entire World WAS laughing and taking advantage of us. People like liddle' Bob Corker have set the U.S. way back. Now we move forward! — Donald J. Trump (@realDonaldTrump) October 24, 2017

The pair are set for an awkward encounter at the Senate Republicans' weekly lunch on Capitol Hill later - with Mr Trump attending for the first time.

The President wants to pass tax legislation by the end of this year, although Mr Trump and his party will have to come together following a number of incidences of internal backbiting.

John McCain, the Arizona senator and Republican 2008 presidential candidate, implicitly criticised Mr Trump for getting a draft deferment during the Vietnam War, although did not mention him by name.

Mr Trump spent much of August criticising Senate Majority Leader Mitch McConnell, blaming him for the upper chamber's failure to repeal and replace Obamacare.

The number three Republican in the Senate, South Dakota's John Thune, appeared to indirectly reference these spats when he said he wants to hear Mr Trump "drive home the message that he wants to be a partner, a constructive partner that helps us get accomplishments that help everybody".

The Trump plan calls for big tax cuts for corporations and potentially for individuals.

The standard deduction used by most Americans would be doubled, the number of tax brackets would drop from seven to three or four and inheritance taxes on multimillion-dollar estates would be scrapped.

But crucial details still need to be finalised, including what income levels would fit with each tax bracket.
