A watchdog group has filed a lawsuit in Colorado arguing that former President Donald Trump should not appear on the states ballot because of his 14th Amendment violations.

The group, Citizens for Responsibility and Ethics in Washington, filed the lawsuit Tuesday in a state district court on behalf of six Republican and unaffiliated Colorado voters who say Trumps actions after he lost the 2020 presidential election are in clear violation of section three of the amendment, which says a person cannot hold state or federal office if they took an oath to support the U.S. Constitution and then violated it by inciting insurrection or rebellion.

Donald Trump has failed this test, the lawsuit states. Four years after taking an oath to preserve, protect and defend the Constitution as President of the United States ... Trump tried to overthrow the results of the 2020 election, leading to a violent insurrection at the United States Capitol to stop the lawful transfer of power to his successor.

The lawsuit rehashes several of Trumps actions on Jan. 6, 2021, when a mob of his supporters stormed the Capitol to stop the certification of the election in favor of President Joe Biden .

The people that Trump mobilized for January 6th were violent extremists and now convicted seditionists whom he earlier instructed to stand back and stand by, the lawsuit said. Many of those who stormed the Capitol were people whom Trump had inflamed for months with the lie that the 2020 election would be rigged and was being stolen from them, the filing states, and Trump encouraged them to march to the Capitol at a rally shortly before the attack.

President Trump was the mobs leader, and the mob was his weapon, the lawsuit states.

The lawsuit comes as Trump faces four criminal trials, with two of them focused on his election subversion efforts: A federal case about his actions around the Jan. 6 attack and state charges in Georgia centered around his attempts to overturn the states election results in his favor.
