House Democrats left a closed-door meeting Tuesday still divided after airing their private views about whether President Biden should remain the party’s nominee.

While the majority of members willing to speak to reporters afterward said they would support Mr. Biden, both those backers and lawmakers who still have concerns said more conversations are needed before Democrats would unify.

“I’m going to let this play out and then I will have something more to say,” House Rules ranking member Jim McGovern said.

While the Massachusetts Democrat declined to say where he stands on Mr. Biden remaining the nominee, he called him “one of the most effective presidents in my lifetime” and said all Democrats seem to agree on that.

But some Democrats said they have outstanding concerns about Mr. Biden’s ability to beat former President Donald Trump in November. Those concerns have intensified since the president’s weak debate performance against Mr. Trump on June 27.

“What you have to see from the president — and this means stop talking about us, stop calling into Morning Joe and saying, you know, I’m frustrated with my colleagues on the Hill — go out there and make the case with the American people about the existential threat that Donald Trump poses to our democracy and our lives,” said Rep. Greg Landsman, Ohio Democrat. “And do it day in and day out for the next couple of weeks, and things will change.”

At least two of the six House Democrats who had publicly called on Mr. Biden to step aside before the meeting — Reps. Lloyd Doggett of Texas and Mike Quigley of Illinois — said they reiterated their concerns in the meeting.

“I share admiration for his work in office,” Mr. Doggett said. “But the dangers of the Trump presidency are so significant that we have to put forward our strongest candidate.”
