From The Washington Post:
U.S. flags at the White House returned to full-staff on Monday morning as the nation continued to mourn the death of Sen. John McCain (R-Ariz.).
The flags were lowered Saturday night following McCain’s death from brain cancer, but Trump did not issue a proclamation calling for flags to remain at half-staff for an extended period, such as through the day of the senator’s interment.
The U.S. code calls for flags to be lowered in the event of the death of a member of Congress “on the day of death and the following day.” But presidents have the power to issue proclamations extending that period.
Presidential historian Michael Beschloss called the move “sickening” during an appearance on MSNBC. Conservative commentator Bill Kristol, meanwhile, wrote on Twitter: “The White House is now an island of bitterness and resentment in a nation united in respect and appreciation.” Others on Twitter responded using the hashtag #NoRespect.
