President Donald Trump will lay out “the path forward” for U.S. strategy in Afghanistan and South Asia in a nationally televised speech Monday night.

The White House announced Sunday that Trump will speak at 9 p.m. Eastern on Monday from Fort Myer in Arlington, Va. Earlier Sunday, Secretary of Defense James Mattis confirmed with reporters that a new strategy had been decided upon.

“I am very comfortable that the strategic process was sufficiently rigorous and did not go in with a pre-set position,” Mattis said, according to Reuters. “The president has made a decision. As he said, he wants to be the one to announce it to the American people.”

On Saturday, Trump tweeted that he was in Camp David with top military advisers. “Many decisions made, including on Afghanistan,” he said.

Earlier this month, Trump was reportedly considering firing the top U.S. general in Afghanistan after becoming frustrated because he was not winning the war. Sixteen years after the war in Afghanistan started, the U.S.-backed government reportedly controls less than 60% of the country, with no end in sight.

In June, Trump gave the Pentagon unilateral authority to boost troop levels in Afghanistan, although there has been no troop surge as of yet.

Monday’s speech will be the first of two important public events for Trump this week. On Tuesday, he is scheduled to speak at a campaign-style rally in Phoenix, Ariz., at which some critics worry he may further inflame racial tensions following his harshly criticized response to the white-supremacist violence in Charlottesville, Va., last week.
