If the basis of convicting former President Donald Trump in this week’s Senate impeachment trial is that his rally speech on Jan. 6 encouraged and incited the violence at the Capitol, then he might have a very simple defense — it didn’t, according to a top Washington lawyer.

And for proof, all Trump’s lawyers have to do is bring forward key law enforcement officials and have them testify that they saw and heard no signals of the coming violence during and after the speech given to a crowd near the White House.
