Congressman #1 is caught cheating on his wife by sexting strange women. The media turns the affair into a three-ring circus, and eventually - under pressure from his own party - the Congressman resigns first his leadership positions, then his seat in Congress.
Congressman #2 is caught cheating on his wife by keeping a mistress, a mistres he first seduced as a practising doctor - she was the patient. Furthermore, despite being "pro-life", he pressured her to abort their unborn child, was reckless with handguns around both wife and mistress, and behaved abusively toward his (soon-to-be ex) wife. The media systematically ignores the story, even after it comes out in court, and then exerts no pressure at all on the Congressman to resign his leadership positions or his seat.
So; who are the congressmen? Be sure to think of your answers before reading the spoiler:
