Washington, Aug 18 (IANS): Former US Vice President Al Gore has said its time for President Donald Trump to leave office.

Gore said in an interview published on Thursday that if he could give Trump one piece of advice, it would be to resign. 

The former Vice President had been highly critical of Trump over his moves to dismantle several high-profile Obama administration environmental policies, Politico reported.

"I thought, actually there was a chance he might come to his senses," Gore said earlier this month, referring to his own December visit to Trump Tower to meet with the then President-elect on climate issues. 

Since that pre-inauguration meeting, Trump has pulled the US from the Paris international climate agreement and also moved to dismantle Environmental Protection Agency rules aimed at curbing greenhouse gases from power plants and automobiles.

During a July interview on NBC's "Today" show, Gore said Trump had "undermined our alliances, such as NATO".

"We've never had a President who's deliberately made decisions the effect of which is to tear down America's standing in the world," Gore said.

The White House did not immediately respond to a request for comment about Gore's advice to the President.
