Several of U.S. President Joe Biden's reelection campaign fundraisers are on hold, multiple Democratic sources involved in the events told Reuters on Friday, even as the Democratic Party planned to accelerate his nomination and he vowed to continue in the 2024 race.

Biden had planned to raise money in Austin, Denver and California next week, but these plans have been shelved, at least for now, the sources said. The president tested positive for COVID-19 on Wednesday but said Friday he would return to the campaign trail next week.

Biden's campaign said his fundraisers would go ahead as planned. "Reuters' sourcing is incorrect, and we look forward to a robust fundraising schedule," campaign spokesman Kevin Munoz said Friday.
