You realize he asked for National Guard on Jan 6th before it ever happened and Nancy Pelosi said no right. She literally said no to the National Guard on Jan 6 and she shot it down. Theres even video of her admitting she should have and was talking about accountability for herself that you can go eatch for yourself
As said by the chief of staff at the department of defense, The speaker of the housr and the mayor are the local governing authorities and its there job to request for the national guard during moments like Jan 6th. Its recorded that DT and the DOD requested to the capital police for NG in advance several times. The capital seargant at arms (who reported to nancy pelosi at the time) denied those several requests saying assistance wasnt needed. The Mayor also denied NG request days in advance
In the case of sending it to LA the scale of this is so much larger that sending in National Guard was required. There are much larger scale riots with Law enforcement being assaulted, property damage, looting, people obstructing officers that it is literally in his listed powers to send in National Guard to something like this. And again he did numerous times try to send NG on Jan6 which lasted significantly less time with way less danger. To be clear I dont condone that either
