Dent, a moderate House Republican who left office in 2017, made the remarks during an appearance on CNN in which he was pressed about whether he supported the impeachment inquiry into President TrumpDonald John TrumpOklahoma City Thunder players kneel during anthem despite threat from GOP state lawmaker Microsoft moving forward with talks to buy TikTok after conversation with Trump Controversial Trump nominee placed in senior role after nomination hearing canceled MORE over his dealings with the Ukraine.

“I certainly would have voted for the impeachment inquiry. Based on the facts as I understand them now, I do think this rises to the level of impeachment. I would probably support it," said Dent, who has long been a critic of the Trump administration.

However, Dent added, "I don’t think the Democrats should move forward on impeachment until they hear from some of these primary witnesses, like John BoltonJohn BoltonThe 'pitcher of warm spit' — Veepstakes and the fate of Mike Pence Senate-passed defense spending bill includes clause giving DHS cyber agency subpoena power Bolton defends Cheney amid clash with House conservatives MORE and Mick MulvaneyMick MulvaneyFauci says positive White House task force reports don't always match what he hears on the ground Bottom line White House, Senate GOP clash over testing funds MORE and the secretary of State himself,” he continued, referring to Secretary of State Mike PompeoMichael (Mike) Richard PompeoGOP scrambles to fend off Kobach in Kansas primary Pompeo: Trump taking action on Chinese software firms 'in coming days' Navarro: 'Don't fall for' message from TikTok lobbyists, 'puppet CEO' MORE.

“I think they need to close that loop. I don’t think they should force this or rush this,” added Dent. “By the same token, neither should the Senate Republicans force or rush a trial.”

During his appearance, Dent also touched on some of the feelings his former colleagues share around the ongoing inquiry.

“Well, I think my former colleagues are in a situation where they understand their base pressure. The base has not yet bolted from the president,” he said. “And I think that’s why they’re standing with the president for the moment.”

“But there’s no question, having spoken to many of them privately, they are absolutely disgusted and exhausted by the president’s behavior. They resent being put in this position all the time,” he continued.

"I think they’d like to step out but they just can’t because of their base at the moment."

The former Pennsylvania Republican said he thinks his former colleagues in Congress can either “be more concerned about their election or their legacies.”

“I would argue to many of them, your legacy is more important than the next election,” he said.

Next week, the House Judiciary Committee is set to hold its first hearing in the investigation and decide whether evidence that has been collected so far in the inquiry warrants bringing forward articles of impeachment against Trump.
