“It is unfortunate that the media, in a rush to judgment, are ignoring the Democratic National Committee’s clear statement that it is wrong to count the votes of superdelegates before they actually vote at the convention this summer,” Michael Briggs said Monday night. 

“Secretary Clinton does not have and will not have the requisite number of pledged delegates to secure the nomination. She will be dependent on superdelegates who do not vote until July 25 and who can change their minds between now and then. They include more than 400 superdelegates who endorsed Secretary Clinton 10 months before the first caucuses and primaries and long before any other candidate was in the race.

“Our job from now until the convention is to convince those superdelegates that Bernie is by far the strongest candidate against Donald TrumpDonald John TrumpKoch-backed group launches six-figure ad buy against Heitkamp Anti-abortion Dem wins primary fight Lipinski holds slim lead in tough Illinois primary fight MORE.”

Superdelegates are party leaders free to vote for any candidate at the Democratic National Convention.

Briggs also called in to MSNBC to talk with Rachel Maddow on Monday night.

"We think it’s important to give the voters their say and not cut off the process at this point," Briggs said. 

He said the campaign is reaching out and making calls to superdelegates "to give another look" at Sanders.

The AP reported Monday night that Hillary Clinton has secured the 2,383 delegates — including superdelegates who say they will vote for her — needed to clinch the nomination for president. 

The AP tally comes ahead of primary elections Tuesday in six states, including delegate-rich California. 

“According to the news, we are on the brink of a historic, historic, unprecedented moment, but we still have work to do,” Clinton said at the start of a Monday rally in Long Beach, Calif., shortly after the AP made the call. 

NBC News announced shortly before 9 p.m. EDT that it would begin calling Clinton the Democrat’s presumptive presidential nominee.
