The President has the troops put there for the inauguration. They would have been there for HIS inauguration . 😢
The troops aren't there for Biden's inauguration. He won't be inaugurated.
Trump is in command of these troops, not Biden. Trump will invoke the Insurrection Act, declare martial law and start to roundup and arrest the co-conspirators of the failed coup attempt against the President and the US government. The NG troops will assist in that operation.
Trump will be president for another four years.
