Republican Senator Bill Cassidy of Louisiana has been defeated in his primary election. The incumbent senator's loss follows active intervention by President Donald Trump against his re-election bid.
President Trump's opposition proved decisive in Cassidy's primary defeat. Senator Cassidy had previously voted to convict President Trump during an impeachment proceeding, a stance that drew the President's public criticism.
This outcome represents a significant victory for President Trump in challenging Republican incumbents. This is a developing story and will be updated as details emerge.
