Could Trump be impeached if it turns out that the Russians have proof that he had sex with an under aged girl when he traveled to Russia?

If it took place in Russia, not the U.S., it may not be against the law there. So whats the problem?

As much as I dislike Trump, what you are saying here is very unfair to the man.

It all depends on what congress wants to do about it. The House of Representatives has to vote on impeachment and then the Senate conducts the "trial" and votes yea or nay on conviction. No president has gotten the yea vote in the Senate before. Probably would have happened to Nixon had he not resigned.

If the House AND the Senate were both controlled by Democrats then Trumps days would likely be numbered. As it is he is protected by the Republicans who currently hold majorities in both houses.

That fake story has been thoroughly discredited.

You think his fans care about that? He has three marriages, two to immigrants, he has children out of wedlock, multiple affairs, bragged about barging into the dressing rooms at Miss America pageants, admitted that his star power allowed he to grab women's crotches, falsely claimed for years that Obama was not born in the US. Trumpbots didn't care about any of that, sleeping with underage girls....well as Jerry Fallwell Jr. said, "we are not electing a Sunday school teacher". Religion only matters to conservatives if you are Muslim.

not unless he was talking tade at the time

Obama has sex with a 10 year old boy and the media covered it up.

No, you can't be prosecuted in America for crimes committed in another country and the age of consent in Russia is 14.

I really don't think his supporters would care if he raped his own daughter.
