Mr. Constitution Hour by Douglas V. Gibbs: President Donald Trump has decided enough is enough, and is sending federal personnel to assist Washington D.C. law enforcement to crack down on crime and homelessness; and the move is legal and constitutional.  Meanwhile, the Texas Democrats who fled the State of Texas over a redistricting vote are returning.  They should not only face fines and jail time for their acceptance of bribery money (O'Rourke's payment of travel, lodging, etc) to influence the vote, but are also subject to federal penalties for violating Article I, Section 4 and Article IV, Section 4 of the United States Constitution.  Mr. Constitution explains.  Plus, we are learning even more about the criminal activities of the Democrats surrounding the giant anti-Trump conspiracy, with Adam Schiff guilty of not only perjury, but leading classified intelligence during the whole Russia Hoax thing.
