Story highlights Hillary Clinton is scheduled to host a fundraiser with top congressional Democrats on June 21 in D.C.

Tester is the latest senator to endorse Clinton, announcing Friday that he was backing his party's presumptive nominee

(CNN) Hillary Clinton will headline a fundraiser with top Senate and House Democrats on June 21 in Washington, according to an invite obtained by CNN.

Clinton, who has seen much of the Democratic Party coalesce around her after she clinched her party's nomination earlier this month, has turned her focused away from Vermont Sen. Bernie Sanders and toward Donald Trump, the presumptive Republican nominee.

Tickets for the fundraiser, which is slated to be larger than most of Clinton's events, start at $2,700. But hosts are expected to raise $27,000.

Clinton will be joined at the event by Sens. Harry Reid, Dick Durbin, Chuck Schumer, Patty Murray, Debbie Stabenow and Jon Tester.

Tester is the latest senator to endorse Clinton, announcing on Friday that he was backing his party's presumptive nominee.
