Haley is still wishy washy on January 6th.
Trump was waiting to see if the January 6th, 2021, Spray Tan Putsch would succeed before making a decision.
As long as it looked like the "Peaceful Tourists" had a chance to delay or disrupt the Cosntitutional Congressional proceeding, Trump was willing to let things play out.
When he realized that the tide was turning against the Putsch, and the "Peaceful Tourists" were already heading home, Trump asked them to leave the Capitol to cover his @$$.
