The
White House has been forced to deny speculation about Donald Trump’s sudden visit to a
Maryland hospital on Saturday for a medical check-up, after it was reported the trip had not followed usual protocol, leading many to wonder whether the president had suffered a more serious health scare.Mr Trump has meanwhile been invited by House speaker
Nancy Pelosi to testify to the impeachment inquiry and “speak all the truth he wants”, a welcome also extended by
Senate minority leader Chuck Schumer, who said the president should give his side of the story on
Ukraine rather than grumble about the proceedings on Twitter.
