WASHINGTON (REUTERS) - The Trump administration is considering Mr Jim Webb, a former Democratic senator who also served as Navy secretary under Republican president Ronald Reagan, to be the next defence secretary, the New York Times reported on Thursday (Jan 3).

Citing an unnamed official, described as a senior Defence Department official, the Times said Vice-President Mike Pence and acting White House chief of staff Mick Mulvaney had reached out to Mr Webb.

It said the official confirmed Mr Webb's name had been circulating at the White House.

Mr James Mattis stepped down from his job as secretary of defence on Tuesday and President Donald Trump said a day later that he had essentially fired Mr Mattis, a retired Marine general whose letter of resignation was seen as a sharp rebuke to the Republican President.

Mr Mattis resigned after Mr Trump's surprise decision to withdraw all US troops from Syria and half of the 14,000-strong contingent in Afghanistan.

Mr Trump has named Mr Patrick Shanahan, a former Boeing executive who was Mr Mattis' deputy, as acting defence secretary.

The Times said Mr Webb could potentially allow Mr Trump to bypass "more hawkish Republicans whose names have been floated to replace Jim Mattis".

It said Republican senators Tom Cotton and Lindsey Graham, and former Republican Senator Jim Talent, had also been mentioned as possible replacements for Mr Mattis.

The White House declined to comment on the Times report.

The Times said Mr Webb did not respond to a request for comment.

Mr Webb, 72, is a decorated war veteran who served in the Vietnam War, the author of 10 books and an Emmy award-winning journalist and filmmaker.

A former US senator from Virginia, Mr Webb ran a long-shot campaign for the 2016 Democratic presidential nomination.

"Americans don't like the extremes to which both parties have moved in recent years and, quite frankly, neither do I," he said in October 2015 when announcing he was dropping his bid.
