According to NBC News, President Joe Biden's top aides have been setting up infrastructure for a possible presidential campaign.

It was reported last month that Biden could run for president in 2024, but he hasn't made a formal announcement.

If the president runs for a second term, he could face Donald Trump again, who has yet to announce a campaign.

Nine people told NBC News that Biden's campaign would have a smaller staff and rely on resources from the DNC.

The DNC is building an infrastructure for him to run and win, according to a former White House adviser.

The Biden administration had several staffers who worked on the campaign follow the president to the White House. According to people familiar with the campaign planning, O'Malley Dillon is expected to play a key role in the Biden campaign.

The announcement of any White House officials leaving to work on the president's campaign is expected in February of next year, according to NBC News.

According to the report, Biden and his staff are considering campaign themes, which could include lauding his in-office achievements as "promises made, promises kept."

Chris Coons told NBC News that the implicit contrast on "promises kept" is clear. The jokes about fixing American infrastructure became a running joke on late-night shows. President Biden was able to get a bipartisan infrastructure investment bill into law.

The representatives from the White House did not reply immediately.
