Most Republicans are neither embracing nor condemning scandal-ridden Rep. Matt Gaetz.

Yet they may soon face a decision day — one they've been happy to avoid, since Gaetz is one of former President Donald Trump's most vocal defenders — and some Republicans are quietly preparing for the real possibility that federal officials will charge the Florida Republican with crimes.

Earlier this month, Gaetz's ex-girlfriend testified before a federal grand jury. She could be a key witness in the Justice Department's probe into whether the Gaetz violated federal sex-trafficking laws and obstructed justice.
