DIsmiss.
Dems counter (along with their media mouthpieces) with "It's just partisan, they don't care about America, they just dismissed because he is a Republican".
Have trial, peel back the rock, expose charges for baseless, discover chargeable offenses by others in the DOJ, FBI, House, and a host of other agencies, remand those for legal action, find POTUS not guilty for lack of evidence of any wrongdoing.
That would put the cork in this nonsense once and for all, and do so in a manner that would expose the very partisan witch hunt that has led us here.
While the whole pile of nonsense should be thrown out, unfortunately it cannot. Especially in an election year.
Lies circle the globe 10 times before the truth gets out of the driveway.
