Donald Trump may not be able to run in Colorado after a group of voters, including Republicans, sued to stop him from being on the ballot over his actions on January 6. They are arguing that because Trump incited an insurrection, the 14th Amendment is barring him from running for any public office.

The former president is currently the frontrunner to win the Republican nomination, as he has a wide lead over all his other Republican opponents. However, he might not be able to win should the lawsuit filed by six Republican and unaffiliated Colorado voters represented by the watchdog group Citizens for Responsibility and Ethics in Washington succeed.

Trump is facing a similar lawsuit in Minnesota, but the Colorado lawsuit happens first, with the first hearing happening in Denver last Monday morning. Should Trump lose the lawsuit, a domino effect could happen in other states, barring him from running in many blue or purple states.

CREW President Noah Bookbinder spoke with ABC News and told the outlet, "It is necessary to defend our republic both today and in the future."

However, the former president has dismissed the 14th Amendment argument with a Trump spokesperson saying, "The people who are pursuing this absurd conspiracy theory and political attack on President Trump are stretching the law beyond recognition."

Witnesses in Denver included two police officers who were at the Capitol on January 6, as well as California Rep. Eric Swalwell.

CREW is also planning to call in two professors as additional witnesses.

"The events on Jan. 6, 2021, in the United States Capitol were horrific. It was a terrorist attack on the United States of America, an assault on democracy, and an attempt to prevent the peaceful transfer of power," testified Officer Danny Hodges, who was one of the officers who defended the Capitol during the January 6 insurrection.

Donald Trump Faces Big Legal Week as Children Also Scheduled to Testify Over New York Fraud Case

As Trump faces disqualification cases in Colorado and Minnesota, he also faces a fraud case in New York. His adult children, Donald Trump Jr. and Eric Trump, are scheduled to testify later this week. Ivanka Trump has also been ordered to testify after the judge quashed her attempts to not take the stand.

While Ivanka was dropped as a co-defendant in the New York fraud trial, prosecutors argued that she could still have information regarding how Trump and Trump Organization executives, including her brothers, inflated their father's assets.

Alabama Man Charged Over Death Threats Against DA Prosecuting Donald Trump

Fulton County DA Fani Willis has been facing death threats from many Donald Trump supporters as the former president has been known to whip up his supporters into acts of violence, as was seen on January 6.

Arthur Ray Hanson II of Huntsville, Alabama has been indicted for leaving threatening voicemails for Willis. On Monday, Hanson claimed he is not guilty of this charge even though the Trump supporter warned Willis to "watch out" in his voicemails because she "won't always have people around who can protect" her.

In one of those voicemails, he told the DA, "When you charge Trump on that fourth indictment, anytime you're alone, be looking over your shoulder," he said, among other things.

He also reportedly threatened the Fulton County sheriff for taking Trump's mugshot, telling him, "If you take a mug shot of the president and you're the reason it happened, some bad (expletive)'s gonna happen to you," and "You gonna get (expletive) up you keep (expletive) with my president."
