"Obama's Strategic Moves to Boost Biden's Campaign Against Trump"

Former President Barack Obama is increasing his involvement in President Joe Biden's campaign due to concerns about a potential win by Republican challenger Donald Trump. Obama is having regular phone conversations with Biden and offering tips to campaign aides, and has committed to many events to stump for his former vice president. This increased level of engagement includes a recent working visit to the White House and an upcoming joint appearance with former President Bill Clinton at a campaign fundraiser. Obama's efforts signal an "all hands on deck" approach to support Biden's re-election bid.
