He will be buried on Sunday in Annapolis, Md.” /> Capitol on Saturday, followed by a national memorial service at the National Cathedral in Washington. He will then lie in state at the U.S.
Through much of Monday, Trump refused to answer reporters' questions about McCain, who refused to support his presidential bid.
WASHINGTON — The White House flag once again was lowered to half staff on Monday after President Donald Trump signed a proclamation to honor John McCain, after much criticism of the way that Trump responded to the Arizona senator's death.
Trump will not attend McCain's memorial services in D.C. but said that he has "asked Vice President Mike Pence to offer an address at the ceremony honoring Senator McCain at the United States Capitol this Friday."
On Monday afternoon, the American Legion urged Trump to sign a proclamation honoring McCain.
"Despite our differences on policy and politics, I respect Senator John McCain’s service to our country and, in his honor, have signed a proclamation to fly the flag of the United States at half-staff until the day of his interment," Trump said in a statement issued by the White House.
He also said that "at the request of the McCain family, I have also authorized military transportation of Senator McCain’s remains from Arizona to Washington, D.C., military pallbearers and band support, and a horse and caisson transport during the service at the United States Naval Academy."
But they were raised on Monday morning, leading to criticism that Trump was unable to put aside political differences to honor McCain, a prisoner of war in Vietnam who went on to serve 35 years in Congress.
