A former top adviser to the Obama campaign expressed his frustration with the pace of gay rights change in an interview on Tuesday.

Steve Hildebrand, the gay man who served as deputy campaign manager for President Barack Obama, expressed his frustration with the pace of the gay rights agenda and other progressive items on Tuesday, telling Politico’s Ben Smith in an interview that he was “losing patience” with the White House.

“I am one of the millions of frustrated Americans who want to see Washington do more than it's doing right now,” said Hildebrand, who was instrumental to Obama’s critical primary victories in Iowa and South Carolina.

Hildebrand said that Obama “needs to be more bold in his leadership,” according to Politico.com.

The remarks, perhaps the most high-profile expression of displeasure to date from Hildebrand, followed his address on August 22 to the San Diego Democratic Club, in which he reportedly delivered a “slashing attack”  against Obama and the Democratic congress.

”The problem is Obama isn’t listening enough,” Hildebrand said at the time.
