A growing number of Democrats who called on Andrew Cuomo to resign as governor amid sexual harassment allegations are now backing his comeback bid for New York City mayor -- including one of his opponents in the race.

Andrew Cuomo faced a two-hour pile-on Wednesday as eight other Democrats vying for the party’s nomination for New York City mayor spent their first debate attempting to knock the former governor off his perch.
