Before Mob Stormed the Capitol, Days of Security Planning Involved Cabinet Officials and President Trump - 2021-01-09

President Donald Trump met with top military officials and gave his approval to activate the D.C. National Guard three days before he encouraged a mob of angry protesters to take their grievances to the U.S. Capitol.
A Pentagon memo released Friday offers these insights, as well as the first detailed timeline of the bungled law enforcement response to Wednesday's insurrection.
The timeline shows that the planning started at least as far back as Dec. 31 and included discussion with select Cabinet members of the potential need for Pentagon reinforcements.
