US President Donald Trump on Tuesday renewed his desire for a full military withdrawal from Afghanistan but added that he had not set a target date, amid speculation he might make ending America's longest war part of his re-election campaign.

"We're there 19 years and, yeah, I think that's enough... We can always go back if we want to," Trump told a White House news conference.

Asked if the Thanksgiving holiday on Nov. 26 was a target, Trump said: "No. I have no target. But as soon as (is) reasonable. Over a period of time but as soon as reasonable."
