Rep. Tim Ryan (D-Ohio) on Saturday doubled down on comments he made last week claiming fellow Democratic presidential candidate Joe Biden is “declining” and lacks the “energy” needed to beat President Donald Trump in 2020.

Ryan told CNN’s Arlette Saenz that he wasn’t “backtracking” when she asked him to clarify remarks he made to a Bloomberg reporter on Thursday.

“It is a concern you’re hearing from a lot of people in the country,” Ryan said at the New Hampshire Democratic Party convention, referring to the former vice president’s campaign. “I’m just saying that it’s unclear sometimes ― when [Biden] is articulating positions there’s a lack of clarity. And I’ll leave it at that.”

Fredricka Whitfield of CNN also grilled him about his dig at Biden in a subsequent interview Saturday, noting that Trump has suggested the Democratic front-runner’s mental agility is waning.

“Are your comments kind of in step with what the president is saying about Biden?” Whitfield asked.

“Well, let me just say that I think President Trump is declining,” Ryan responded. “He’s very forgetful. He’s not as sharp. He’s lost a lot in the last couple years.”

Ryan added that he’s been “hearing on the ground” that people are at times concerned by Biden’s “lack of clarity.”

“We’ve got to make sure that we send someone to take down Donald Trump who can articulate a very clear vision for the country in a very forceful and firm way and do it in all 50 states all over the country,” Ryan said.
