2024 election updates: Manchin the latest to call on Biden to end reelection bid

The Biden campaign is laying out what it sees as its path forward to Joe Biden winning reelection in a new memo shared internally with campaign staff on Thursday by Jen O'Malley Dillon and Julie Chavez Rodriguez, a source familiar with the campaign told ABC News.

The memo, first reported by the AP, acknowledges anxieties but claims they still have "multiple pathways to 270 electoral votes."

The memo was revealed after Democrats had demanded Biden and his campaign show how it planned to win despite Biden's poor poll numbers.

The campaign said it will focus on winning the “blue wall” states of Wisconsin, Pennsylvania and Michigan, and believes that the "sunbelt states are not out of reach."

The memo states the race remains a margin-of-error race in key battleground states, despite calls for Biden to step down citing internal data.

Sen. Peter Welch, D-Vt. spoke with ABC News Thursday morning about Thursday's scheduled lunch between Democratic senators and top Biden campaign officials.

Welch, who is, so far, the only Democratic senator to call for Biden to step aside, said the path forward involved the president persuading voters, not advisers persuading senators.

"It's a show me not tell me issue. I think for Americans it's not so much about individual senators or members of Congress," Welch said. "It's really about the challenge of everyday campaign."

Sen. Sheldon Whitehouse, D-R.I., told ABC News he's putting a bit more weight into Thursday's meeting with the Biden officials.

"We are very interested to hear how they make their case," he said.

Michigan Rep. Hillary Scholten has added her name to the growing list of House Democrats who are calling on Biden to end his presidential election bid.

The congresswoman said in a statement posted on X Thursday that it "is essential that we have the strongest possible candidate leading the top of the ticket -- not just to win, but to govern."

"The people of Michigan’s 3rd Congressional District elected me to represent them with integrity. They elected a Congresswoman they trust to speak the truth, even when it’s hard. They voted for someone who would put America's future first and stand up for what is right. That's what I am doing now," Scholten, who represents Grand Rapids, said.

She is the 10th sitting House Democrat to call for Biden to step aside.

Scholten noted that if Biden stayed in the race, she would "respect his decision," and still vote for him.

The White House announced Thursday morning that the much-anticipated Biden's press conference will now start at 6:30 p.m. local time in Washington, instead of the previous 5:30 p.m. start time.

Biden has a busy day of meetings tied to the NATO summit ahead of the press conference, including a meeting with Ukrainian President Volodymyr Zelenskyy.

The presser will be held at the Walter E. Washington Convention Center, and is his first solo press conference in eight months.
