Biden slams predecessor in campaign trail

US President Joe Biden opened his reelection campaign by denouncing his predecessor and likely opponent in 2024, while former president Donald Trump described Biden's speech as "fearmongering" and downplayed the violence on Jan 6,2021, in his campaign trial.

The key issue in November's election is that "democracy is on the ballot", Biden said on Friday, the eve of the third anniversary of the Jan 6 attack on the US Capitol. Biden spoke at an event in Pennsylvania, a key state in the 2024 election.

Trump on Friday and Saturday hit back at Biden.
