President Obama preparing to endorse Hillary Clinton

WASHINGTON — President Barack Obama is ready to make it official.

As Hillary Clinton secured the delegates needed to become the presumptive Democratic presidential nominee, Obama was on the verge of formally endorsing his former secretary of state. And then he plans to aggressively make the case against Republican Donald Trump. White House officials say the announcement could come within days, although not before Democrats in New Jersey, California and four other states vote Tuesday in contests expected to solidify Clinton's claim.
