There should be a way for them to sue Biden himself, or at least only include those who voted for him. Those who object to these policies should not be sued just because we are US taxpayers.
Rep. Ronny Jackson needs to call not only a Section 3 violation of the 14th Amendment for all members of Congress who voted to support the constitutionally indefensible foreign aid in Pelosi's unconstitutional omnibus bill, but he also needs to have Biden impeached for signing Pelosi's unconstitutional bill into law.
"14th Amendment, Section 3: No person shall be a Senator or Representative in Congress, or elector of President and Vice President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof [emphases added]. But Congress may by a vote of two-thirds of each House, remove such disability."
“If the tax be not proposed for the common defence, or general welfare, but for other objects, wholly extraneous, (as for instance, for propagating Mahometanism among the Turks, or giving aids and subsidies to a foreign nation, to build palaces for its kings, or erect monuments to its heroes,) it would be wholly indefensible upon constitutional principles [emphases added].” — Justice Joseph Story, Commentaries on the Constitution 2 (1833).
"Congress is not empowered to tax for those purposes which are within the exclusive province of the States." —Justice John Marshall, Gibbons v. Ogden, 1824.
“Cherish, therefore, the spirit of our people, and keep alive their attention. If once they become inattentive to the public affairs, you and I, and Congress and Assemblies, judges and governors, shall all become wolves [emphasis added]. It seems to be the law of our general nature.” - Thomas Jefferson (Letter to Edward Carrington January 16, 1787)
Emphasizing that desperate Democrats will always find a way to weaponize government power against the people, Congress needs to establish a court that does nothing but hear alleged federal and state violations of Section 3.
The Section 3 court would undoubtedly put Congress out of business right away!
Any member of Congress who is not on record as supporting a veto override of a bill to establish a Section 3 court needs to get primaried in 2024.
