This suit could erase the sovereign immunity of federal elected officials.
Not without repealing part of the Constittion.

U.S. Const., Art. 1, Sec. 6
The Senators and Representatives shall receive a compensation for their services, to be ascertained by law, and paid out of the treasury of the United States. They shall in all cases, except treason, felony and breach of the peace, be privileged from arrest during their attendance at the session of their respective Houses, and in going to and returning from the same; and for any speech or debate in either House, they shall not be questioned in any other place.

Article 3, Sec. 3:
Treason against the United States, shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort. No person shall be convicted of treason unless on the testimony of two witnesses to the same overt act, or on confession in open court.
For treason, real wartime enemies are required along with a real war.
Only fools believe treason happens only during war and not during even relative peace.
Treason leads TO war, not from it.
