Robert F. Kennedy Jr. said Friday he is still "listening" to arguments about the assault on the U.S. Capitol by a pro-Trump mob on Jan. 6, 2021, to try to "hear every side," and suggested without evidence, prosecutions of the rioters have been politically motivated.

       Kennedy, who is running for president as an independent, also expressed skepticism that the events that day constituted an "insurrection." He said that "reasonable people, including Trump opponents, tell me there is little evidence of a true insurrection."

       The comments were part of a lengthy statement Kennedy released to try to "clarify" his views on Jan. 6 -- an apparent response to the backlash he received for a fundraising email his team sent calling Jan. 6 defendants "activists."

       Kennedy's campaign blamed an outside vendor for the email, which was blasted to supporters on Thursday by "Team Kennedy" and stirred controversy after NBC News reported on it. A campaign spokesperson said they've since stopped working with the vendor.

       "That statement was an error that does not reflect Mr. Kennedy's views," a spokesperson told ABC News in a statement. "It was inserted by a new marketing contractor and slipped through the normal approval process. The campaign has terminated its contract with this vendor. Anybody who violated the law on Jan. 6 should be subject to appropriate criminal and/or civil penalties."

       But Friday's statement, rather than clarifying Kennedy's stance on Jan. 6, instead said he is still forming an opinion about what happened that day and the future of those imprisoned for taking part.

       He said that as president, he would appoint a special counsel to "investigate whether prosecutorial discretion was abused for political ends in this case, and I will right any wrongs that we discover."

       Federal prosecutors have charged more than 1,265 defendants across nearly all 50 states and Washington, according to data released in January by the U.S. Attorney's Office in D.C. They secured sentences of incarceration for more than 460 people, and hundreds of others have been sentenced for lesser offenses to periods of home detention or probation.

       "I am concerned about the possibility that political objectives motivated the vigor of the prosecution of the J6 defendants, their long sentences, and their harsh treatment," Kennedy said. "That would fit a disturbing pattern of the weaponization of government agencies – the DoJ, the IRS, the SEC, the FBI, etc. – against political opponents."

       While Kennedy said he has not "examined the evidence in detail," he claimed some have observed the protesters "carried no weapons, had no plans or ability to seize the reins of government, and that Trump himself had urged them to protest 'peacefully.'"

       But according to the U.S. Attorney's Office in D.C., more than 200 people have pleaded guilty to felonies that include assaults on federal officers, obstructing law enforcement and seditious conspiracy. Plus, 123 people had been charged with using a deadly or dangerous weapon or causing serious bodily injury to an officer.

       There is also video evidence of rioters carrying everything from stun guns, knives and batons to chemical irritants spray, sticks or even flags used to stab or strike any number of officers trying to protect the building that day.

       Attorney General Merrick Garland defended the department's integrity in prosecuting these cases and characterized Jan. 6 as "an unprecedented attack on the cornerstone of our system of government: the peaceful transfer of power from one administration to the next."

       "In the ongoing Jan. 6 investigations and prosecutions led by the U.S. Attorney for the District of Columbia Matt Graves and Special Counsel Jack Smith, the Justice Department is abiding by the longstanding norms that ensure independence and integrity of our investigations," Garland said in January as he marked the three-year anniversary of the attack. "We are following the facts and the law wherever they lead. We are enforcing the law without fear or favor. We are honoring our obligation to protect the civil rights and civil liberties of everyone in our country. We are upholding the rule of law, and we are protecting the American people."

       In an interview last month on Fox News, Kennedy was asked whether he would pardon any Jan. 6 defendants.

       "That's not something I would comment on until I'm president of the United States," he said, later adding, "I would look at any individual cases."
