So far, playing to the left, the base through leaks to friendly Media. No Law has been broken, just some holdover bureaucrats, deep state types, who don't like how the Boss talks to others, believe they are in charge of US Foreign Policy, since no one has challenged them before, from any Administration.
Dems are eager for anything, seeking ways to avoid actually winning the 2020 election against President Trump. Media loves it and those who do not follow it all closely are willing to believe actual drama is occurring in Washington.
Democrats, and Media, need to move quickly to take the air out of the room, before the DOJ reports are completed regarding Intelligence, Obama Admin folk and their involvement with the 2015 and 2016 efforts to derail Trump's election, then to negate it early in his Presidency, and even up to the present.
Need a counter to what is expected soon, as Clapper, Brennan, and the rest f the culprits begin to sing, to save their hides...
Once Democrats tire of using secret hearings, or actually find something they can explain as ILLEGAL, some LAW that was broken by the President, or once the DOJ reports begin to be made public and charges become real, the Dems may decide upon Impeachment, and bring charges via Judiciary Comm, which will be public. Democrats still have the majority in the House, and will make full use of their powers, I am sure.
Is still Theater Time, searching for something they think will 'stick' and not bite them all in the next election. Until then, drive down Trumps poll numbers and try to convince themselves it is all worth it.
