Trump pleads not guilty on Jan. 6 charges, calls it 'sad day for America’

Former President Donald Trump pleaded not guilty to all counts after being charged in connection with his alleged attempts to overturn the result of the 2020 presidential election.

The new 45-page federal indictment, unsealed Tuesday, accuses Trump of four felony counts: conspiracy to defraud the United States, conspiracy to obstruct an official proceeding, obstruction of and attempt to obstruct an official proceeding, and conspiracy against rights.

It's the third time that Trump has been indicted on criminal charges. He has pleaded not guilty to all charges in the two other cases, decrying the investigations as political witch hunts. He continues to insist that the 2020 vote was rigged and, speaking to ABC News on Tuesday, described the latest charges as a "pile-on" and "election interference."

Current and former U.S. Capitol Police officers who were at the Capitol during the Jan. 6 attack reacted to former President Donald Trump's indictment following his arraignment on Thursday.

U.S. Capitol Police officer Harry Dunn told ABC News Live the indictment reflected "equal justice under the law" being applied.

"It's a necessary step on the road, the path to justice and accountability," Dunn said. "I didn't expect much from this hearing arraignment. I didn't learn anything new. But it was good to see former President Trump facing accountability just like any other person in this country would if they committed the crimes that he did."
