I would apply this rule to the ex-presidents to put an end to their deliberate attempts to undermine the current one - the Obongo style.
obongo knows Trump is going to expose his involvement in collusion right along with Crooked Hillary.
Remember when obongo was standing in front of the open microphone, that he thought was turned off, and told Putin, " I will have more flexibility once I am in office." :-o
Now you have Shifty Schiff making up lies about Trump and telling them to Congress as well as the American people of things Trump never said only Shifty Schiff got caught red handed because the transcript he was reading from never said any such thing.
Shifty improvised with his own words of what he wanted it to say and not what it actually said.
Trump should sue that s.o.b. for deformation and obstruction. (Go to jail)
You can't make this stuff up that the bias media and Libs keeps sweeping under the rug like it never happened.
under pressure from the Bully-in-Chief, and were simply too scared to fight back.
You bet criminals are scared of Trump exposing their collusion and only a fool would try to fight the truth at this point knowing that they will end up in prison.
That is why there will be no impeachment in fear they will be subpoenaed and put under oath.
Crooked Hillary has never had to testify under oath about her collusion yet.......but she would if there is an impeachment.
The Clinton Foundation is presently under investigation which is going to expose a lot of people of a lot of criminal activity.
Lock her up !
