President Donald Trump's pardons of those convicted in the Jan. 6, 2021, attack on the U.S. Capitol and the rhetoric of retribution from some of those released this week is raising deep concern among attorneys, former federal investigators and experts who follow extremism.

More than 800 people across the U.S. have been charged in the Jan. 6 riot at the U.S. Capitol.

An independent review has concluded that the Defense Department and its top leaders acted appropriately before and during the Jan. 6 insurrection at the U.S. Capitol.

Jacob Chansley, the spear-carrying Jan. 6 rioter whose horned fur hat, bare chest and face paint made him one of the more recognizable figures in the assault on the Capitol, has been sentenced to 41 months in prison.

An Arizona man who sported face paint, no shirt and a furry hat with horns when he joined the mob that stormed the U.S. Capitol on Jan. 6 pleaded guilty Friday to a felony charge.

At least a dozen of the 400 people charged in the Jan. 6 insurrection at the U.S. Capitol have made questionable claims about their encounters with officers while inside the building.

A month later, he wrote an apology from jail, asking for understanding as he was coming to grips with his actions. Confronted with compelling video and photographic evidence in court, dozens of rioters have apologized and expressed regret as the consequences of their actions have started to sink in. Ad“This is going to have consequences for these people for the rest of their lives — and it should,” said John Flannery, a former federal prosecutor and Capitol Hill lawyer. He later went to the trouble of putting a finger emoji on the photo pointing to a fuzzy image of someone by the tunnel. “We are good people who care deeply about our country,” Chansley wrote.

A judge ordered corrections authorities to provide organic food to an Arizona man who is accused of participating in the insurrection at the U.S. Capitol while sporting face paint, no shirt and a furry hat with horns. Since being jailed, Chansley has had two instances in which he wasn’t eating because the detention facilities where he was being held didn’t serve organic food. AdLast week, a judge ordered corrections officials to provide Chansley with organic food. He was later moved to a jail in Virginia after the District of Columbia Department of Corrections said it couldn’t honor the court’s order to feed him organic food.

Or you can venture up East River Mountain to Crossroads Church, where Pastor Travis Lowe eschews Bradford’s fiery political rhetoric, seeking paths to Christian unity.

But Mercer County gave more than three-quarters of its votes to Trump, and Bradford and his pronouncements are very much in line with that.

(AP Photo/Manuel Balce Ceneta, File)WASHINGTON – A man who stormed the U.S. Capitol while sporting face paint, no shirt and a furry hat with horns was moved to a jail in Virginia on Thursday after a federal judge ordered authorities to provide him with organic food while he's in custody. A judge ordered corrections officials to provide the special diet. Chansley, who calls himself the “QAnon Shaman,” considers eating organic food to be part of his “shamanic belief system and way of life,” the lawyer said. Chansley told investigators he came to the Capitol “at the request of the president that all ‘patriots’ come to D.C. on January 6,” according to court records.

Chansley’s attorney told a federal judge Wednesday that his client is not getting enough organic food in jail and he hasn’t eaten in more than a week.

Wednesday’s news comes after the D.C. jail denied Chansley’s request on Tuesday to eat only organic food. Officials said he wasn’t able to name a religious need for organic food. But the judge decided his religious belief and having been fed organic food in an Arizona jail were enough reasons to adjust Chansley’s diet.

(AP Photo/Evan Vucci, File)WASHINGTON – The words of Donald Trump supporters who are accused of participating in the deadly U.S. Capitol riot may end up being used against him in his Senate impeachment trial as he faces the charge of inciting a violent insurrection. For weeks, Trump rallied his supporters against the election outcome and urged them to come to the Capitol on Jan. 6 to rage against Biden's win. And if they can show that Trump’s words made a real impact, all the better, and scholars expect it in the trial. Another man, Robert Bauer of Kentucky, told FBI agents that “he marched to the U.S. Capitol because President Trump said to do so,” authorities wrote.

When supporters of former President Donald Trump violently broke into the U.S. Capitol on Jan. 6, the melee left five people dead, including a Capitol police officer. Even though many of the rioters waved Trump flags and wore Trump hats, some Republican politicians quickly blamed the intrusion on Antifa. According to Bray, Antifa gained new prominence in the United States in 2017 after a clash with the white supremacist, Unite the Right Rally in Charlottesville, Virginia. “The left in America has incited far more political violence than the right,” Gaetz has also said on the floor of the House of Representatives. Based on information from the FBI, the Anti-Defamation League and a historian, we give the claim of Antifa being involved in the attack on the Capitol a rating of Not True on the Trust Index.

The Office of the Pardon Attorney, which handles these reviews, did not respond to a request for comment, but former federal prosecutors said Trump giving clemency to those at the Capitol would be highly unusual.
