Great, this bit of FAKE NEWS has been debunked.  Even Christ Matthews agrees there was no collusion.   Let's move on with building the wall, deporting any illegals ICE bumps into, passing a law that every single business must use E-Verify when hiring every employee, cutting off all aid to illegals, do not allow anyone into this country who can not be fully vetted.  As to terrorists, this is easy.  ANYONE caught carrying pipe bombs and a plan of Ft. Dix, plotting terror, building bombs, is immediately arrested, tried and jailed.  Commit a terror attack and live through it?  You get the death penalty by firing squad since you are at war with America, you are the opposing army and need to be dealt with by the military.  The FAMILY of every terror plotter or terrorist who succeeds must be immediately finger printed, DNA tested, and quickly deported.  Any resources they have acquired  in the U. S. A. are forfeit and will be sold and the proceeds given to victims of terror.  Include McVeighs
