US Defence Secretary Announces Resignation... Hints At Policy Differences With Trump

US Defence Secretary James Mattis is resigning, the latest in a string of senior US officials to do so.

His announcement came a day after President Trump said he was withdrawing troops from Syria - a decision General Mattis is understood to oppose.

In his resignation letter, Gen Mattis strongly hinted at policy differences with Mr Trump.

He said the president had the right to appoint someone "whose views are better aligned with yours".

Gen Mattis, 68, will leave the job in February. President Trump has not immediately named a successor, but said one would be appointed shortly.
