Republicans fail to ease one of Trump's greatest fears as Supreme Court measure collapses

House Democrats are nuking Republicans' effort to assuage one of President Donald Trump's biggest concerns about the future of the federal government.

A vote on a constitutional amendment to cap the number of Supreme Court justices failed on Wednesday afternoon after the vast majority of Democrats voted against it.

Biggs posed on Wednesday.
