The dems have control of the house, so they can do what ever they want. But to breach Executive Privilege, they are going to need real probable cause and a full vote of the house. At least that is the way I see it with my limited knowledge. Then there is Trumps agenda which is not liked by majorities in both the political branches. I think the dems are thinking that by doing this, Trump has to keep his party happy so they will not vote to remove after impeachment. But Trump’s move today in Syria shows Trump will not play by that. If this is all about the 2020 elections, I think the dems are in trouble. But if the Senate were to vote to remove Trump, the dems would run the table in 2020. The repubs have control here, but they have a history of snatching defeat from the jaws of victory.
The GOP Senate has a choice. Remove Trump and lose big.
Keep Trump and deal with him for 4 more years. And many of those senators were used to getting kickbacks to their family. On one hand they lose power & money and the other they lose only money.
Notice how the term “Constitutional Crisis” isn’t being tossed around like it was during the Clinton Impeachment?
