Some urged the President to address the nation, as a way to rally Americans.
"Americans are looking for leadership," said Rep. Jim Banks (R-IN), in a direct Twitter appeal to the President.
Instead, the President attacked Democrats, and his likely opponent in November.
"The World is watching and laughing at you and Sleepy Joe. Is this what America wants? NO!!!" Mr. Trump wrote.
While the President stayed out of sight on Sunday, former Vice President Joe Biden went into his home town of Wilmington, Delaware to meet with protesters.
"We are a nation exhausted, but we will not allow our exhaustion to defeat us," Biden said in a statement on Instagram.
"The President hid in the White House bunker because there were protesters across the street," said Rep. David Cicilline (D-RI).
"Tells you all you need to know," Cicilline added.
