The former secretary of state and potential presidential candidate is headlining Brown's 5 p.m. event at a wooded 2.8-acre estate in the wealthy Washington suburb. Tickets cost $4,000 each — even more for VIP tickets, according to an event invitation.
Brown campaign manager Justin Schall said as many as 500 people might attend and the campaign expects to raise more than $1 million — a sum greater than that garnered during a May fundraiser for Brown featuring former President Bill Clinton.
Hillary Clinton has stepped up her political appearances in recent weeks, with events scheduled for Florida, Nevada, New York and New Hampshire to help other Democrats in the midterm elections. Clinton, a new grandmother, postponed another fundraiser that had been planned for today — for a New Hampshire state senator — according to the New Hampshire Journal. On Friday, the Clintons' only daughter, Chelsea, gave birth to the couple's first grandchild, a girl.
As of late Monday, Hillary Clinton was still expected in Maryland for Brown's event. If she comes, Clinton will not be the only potential 2016 presidential candidate on the grounds. Gov. Martin O'Malley also plans to attend.
The high-profile, high-dollar event comes during a bitterly fought campaign for Maryland's governor.
The Democratic Governors Association has put more than $750,000 behind attack ads against Brown's Republican opponent, Larry Hogan.
The Republican Governors Association, in turn, sent its chairman, New Jersey Gov. Chris Christie, to Maryland this month for a fundraiser to benefit Hogan.
Hogan campaign spokesman Adam Dubitsky used Clinton's appearance in Maryland to fire a salvo at Brown.
"Unlike the Clinton White House, which worked with Republicans to grow the economy, cut the deficit and create jobs, Anthony Brown is committed to extending the failed policies of one-party rule, his 40 job-killing tax hikes and reckless spending," Dubitsky said. "So, other than payback for Anthony Brown endorsing her for president over Barack Obama, we have no idea why Secretary Clinton would associate with him."
Both Brown and O'Malley were early backers of Clinton in the 2008 Democratic fight for the presidential nomination, then threw their support behind Obama after he won the primary.
