"I will be lowering the flags on all Federal Buildings and National Monuments to half-staff over the next three days in memory of the Americans we have lost to the CoronaVirus," he tweeted.

In a subsequent tweet, Trump wrote that on Monday, "the flags will be at half-staff in honor of the men and women in our Military who have made the Ultimate Sacrifice for our Nation."
