'Sick man': Widower threatens embattled GOP Rep with more 'salacious' messages

The husband of Rep. Tony Gonzalez's late aide, who took her own life after being involved in an affair with the Congressman, spoke out on Wednesday during an interview on CNN.

Adrian Aviles, the widow of Regina Santos-Aviles, spoke to CNN's Erin Burnett about the evidence he still has against Gonzalez. The lawmaker has faced growing calls to resign after text messages surfaced between himself and Santos-Aviles that appear to show him coercing her into a sexual relationship.

The Congressman has denied any wrongdoing.
