TRUMP JR under investigation :), page-111

You have expressed the opinion that "Trump called for a peaceful protest". But you claim to have no opinion on wether Trump is lying when he made these claims in his speech

"All of us here today do not want to see our election victory stolen by emboldened radical-left Democrats, which is what they’re doing. "

"We will stop the steal. Today I will lay out just some of the evidence proving that we won this election and we won it by a landslide."

He and his legal team have never presented the slightest evidence that stood up in court so they are not just Trumps "opinion". They are baseless and dangerous lies which he has repeated constantly for weeks. The entire "stop the steal" is based on lies and he repeated these lies throughout the entire speech.
Because his supporters acted on the basis of a pack of conscious lies repeated by Trump and Giuliani, and presented as the truth, then Trump is entirely responsible for the death and destruction caused by his supporters.
Impeachment was letting him off too easy.
