Trump backs Ken Paxton in crucial Texas Republican Senate run-off

Key Points:

• Former President Donald Trump has endorsed Texas Attorney General Ken Paxton in the Republican run-off for the US Senate seat, criticizing incumbent Senator John Cornyn for allegedly not supporting him during difficult times.
• Cornyn denied Trump's claims, highlighting his close cooperation with Trump during his presidency and asserting he has been a consistent ally.
• Paxton, despite controversies including felony indictments and impeachment, remains a strong contender in the Republican primary but faces concerns from some Texas Republicans about his electability in the general election.
• Polls show a tight race between Paxton and Cornyn in the run-off, with Democrats' James Talarico competitive or leading in potential general election matchups against both Republicans.
• Political analysts warn that Trump's endorsement of Paxton could strain his relationship with Senate Republicans, particularly if Cornyn loses, and some Republicans have publicly questioned Paxton's ethical standing.
