WASHINGTON (REUTERS) - US President Donald Trump said in his State of the Union address to the US Congress on Tuesday (Wednesday morning Singapore time) that he wants lawmakers to support the "right to try" for terminally ill patients to try experimental therapies not approved by federal authorities.

"It is time for the Congress to give these wonderful Americans the 'right to try,'" Trump said.

Legislation along these lines was approved by the Senate in August by a vote of 94-1. It was designed to give terminally ill patients access to unapproved medications and to provide immunity for physicians willing to administer the treatments.

Trump has expressed support for the measure before.
