Washington/UNI: US President Joe Biden will indicate his plans to run for re-election in the next few weeks, US newspaper The Hill reported citing sources familiar with preparations for the 2024 campaign bid.

"It's still very much in the works and nothing has changed," a source in the know was quoted as saying.

The 80-year-old is expected to signal his intention to run in the state-of-the-union address to the nation on Feb 7 and make a more formal declaration closer to the spring.

This is despite the ongoing controversy surrounding the find of classified documents at Biden's private office in Washington, DC.

The scandal has dominated White House briefings in January, stirring uncertainty among his Democrats, the paper has learned.

A Democratic strategist who spoke to The Hill on condition of anonymity said the issue was overtaking the campaign.

It has allowed Republicans to draw parallels between Biden and his predecessor, Donald Trump, who has his own secret papers scandal to deal with.
