Donald Trump took to the golf course as John McCain's daughter made a withering eulogy at the funeral he was barred from attending.
Senator McCain died last Saturday following a battle with brain cancer and had previously said he did not wish for the president to attend his funeral.
While former U.S. presidents Barack Obama and George W. Bush attended the service, Trump tweeted on subjects ranging from Canada to the FBI while hitting the golf course.
