A White House official told CNN that aides to the President went to Trump to have him make the order to deploy the National Guard to the US Capitol.
The official said aides also asked that Trump record a video calling for an end to the siege on the Hill.
In other words, these were not decisions Trump made on his own. Aides went to him to get him to do it.
A source familiar with the situation said White House staffers are "horrified" by the violence at the Capitol and are worried there will be more trouble on the streets tonight.
