Even better is Trump's pretty much definitive obstruction of justice.
Are you referring to the memo that Comey wrote, saying that Trump asked him to stop the investigation into Flynn?
Or are you referring to Trump's statement about "releasing tapes" (that some see as a veiled threat to Comey)?
This can't last too much longer.
Actually yes it can.
While the occasional republican have made the occasional "Bad Trump" comment, overall the republicans have shown an almost complete lack of morality as of late, and are only interested in maintaining power. (Just look at Devin Nunes, who is supposedly someone responsible for investigating Trump wrong-doing, but seemed to be more interested in providing political interference, and investigating the bogus wiretap claim.) So while you may get a few republican congressmen complaining about some of Trump's actions, they won't make any effort to actually
stop him (through impeachment or other means), because, well, he's a fellow Republican who can help ensure tax cuts to the wealthy.
