Here's my take on it.
House Democrats will now have the power to investigate and vote on articles of impeachment. Knowing that it would then take two-thirds of the Senate to convict, the House findings combined with Mueller's report could be so overwhelming that the Senate could be compelled to convict. It's even possible that Pence could also be impeached and convicted. Keep in mind that new House Speaker Nancy Pelosi is third in line for the presidency.
My guess is that House Democrats will not rush to impeach Trump - but I feel certain they will investigate the hell out of him and let the chips fall where they may. Mueller's findings will be paramount in whatever they decide.
Well, that's my take on it. What do you think?
