Donald Trump has ramped up his calls for his Republican rivals to drop out of the 2024 presidential race during a rally in Pennsylvania.

He called on primary Republican members of Congress to focus on investigating President Joe Biden and urged them to halt Ukrainian military aid until the White House co-operates with their investigations into Mr Biden and his family.
