The flags at the U.S. Capitol, meanwhile, remained at half-staff on Monday to honor the Arizona Republican, who died Saturday of brain cancer.
President Donald Trump offered his condolences on Twitter to McCain’s family but hasn’t issued a presidential proclamation with an order lowering the flags. The two had a long-running feud.
U.S. Flag Code states that flags be lowered “on the day of death and the following day for a Member of Congress.”
After Democratic Sen. Ted Kennedy of Massachusetts died in 2009, President Barack Obama ordered flags at the White House be flown at half-staff for five days.
The White House didn’t immediately respond to questions Monday.
