The Associated Press is reporting that Hillary Clinton has captured commitments from the number of delegates needed to become the Democrats’ presumptive nominee.

Clinton, the former secretary of state, New York senator and first lady, reached the 2,383 delegates needed to become the presumptive Democratic nominee on Monday with a decisive weekend victory in Puerto Rico and a burst of last-minute support from superdelegates, according to the news agency.

Those are party officials and officeholders, many of them eager to wrap up the primary amid preference polls showing her in a tightening race with presumptive GOP nominee Donald Trump.

Clinton has 1,812 pledged delegates won in primaries and caucuses. She also has the support of 571 superdelegates, according to an Associated Press count.

While superdelegates will not formally cast their votes for Clinton until the party’s July convention in Philadelphia, all those counted in her tally have unequivocally told the news agency they will do so.

Clinton outpaced Sanders in winning new superdelegate endorsements even after his string of primary and caucus wins in May. Following the results in Puerto Rico, it is no longer possible for Sanders to reach the 2,383 needed to win the nomination based on the remaining available pledged delegates and uncommitted superdelegates, according to the report.

The report comes just after it was speculated that President Barack Obama could endorse Clinton as soon as this week, though the White House has remained non-committal about that.

The president reportedly spoke with Sanders, over the weekend, though the White House declined to comment on the contents of the conversation.

Clinton has recently shifted the focus of her campaign from Sanders to Trump.

Last Thursday, Clinton gave a speech in San Diego in which she blasted Trump’s  foreign policy platform, which she described as “dangerously incoherent”.
