The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened) against domestic Violence.
—US Constitution, Article IV, Section 4
^^^^^^^^^^^^^^^^^^^^^^^^^^
The declaration of invasion by a state government puts the onus on the federal government to react by protecting that state. Failure to do so becomes dereliction of duty. That also constitutes an impeachable offense should a president fail to do his duty.

thanx for citing from the constitution.
yes, this border issue is setting up zho bai din for impeachment......on an issue that’s easy for everyone to understand.
Congress is the first branch of government as defined within the Constitution. One of the duties of Congress is to hold the other branches' feet to the fire. If Congress fails to launch impeachment once an obvious violation of the Constitution occurs (invasion), then Congress is in mortal danger from the people.
