WASHINGTON (CNN) - Hillary Clinton's deputy campaign manager has resigned, her campaign confirmed Tuesday night as the New York senator faced another round of disappointing primary results.
Mike Henry is the second senior staff-level departure from the Clinton team in the past three days. He was hired by Patti Solis Doyle - Clinton's former campaign manager - whose resignation was revealed Sunday.
"As someone who has managed campaigns, I share the unique understanding of the challenges that the campaign will face over the next several weeks," Henry said in a Tuesday e-mail to Clinton staffers.
"Our campaign needs to move quickly to build a new leadership team, support them and their decisions and make the necessary adjustments to achieve the winning outcome for which we have all worked so hard for over a year now."
Howard Wolfson, spokesman for Clinton's campaign, said that Henry had done "an outstanding job for the campaign and his expertise will be missed."
Henry, who helmed the Democratic Senatorial Campaign Committee's independent expenditure program two years ago, was the author of an internal memo last year that suggested Clinton should skip Iowa - a proposal that was quickly dismissed when it became public.
A year earlier, he managed the successful campaign of Virginia's Democratic Gov. Tim Kaine, and was a lead advisor to former Virginia Gov. Mark Warner's campaign.
CNN projects that Clinton's rival for the Democratic presidential nomination, Illinois Sen. Barack Obama, won Tuesday night's Virginia Democratic primary.
