Missouri lawmaker has broken from the Republican line and slammed President Donald Trump for deploying the National Guard in Washington, D.C.

Some National Guard units patrolling the nation’s capital at the direction of President Donald Trump have started carrying firearms, an escalation of his military deployment that makes good on a directive issued late last week by his defense secretary.

The exact number of troops who would carry their weapons was fluid, but they will either carry M17 pistols or M4 rifles, according to officials who spoke on condition of anonymity.
