US congressman refuses to drop re-election bid over ex-wife's abuse claims

A US congressman who is battling abuse allegations from his ex-wife and her father, a US senator, has vowed not to quit.

Ohio Republican Max Miller, who is fighting for his political life on the eve of a deadline to file for re-election, told CNN: "I'm never going to back down."

He acknowledged that President Donald Trump had phoned him on Monday to express doubts about his ability to win in November.
