Congressman Denny Rehberg, Karen Hinton, and Erick Mullen Join Mercury/Clark & Weinstock in Washington, DC

Washington, D.C.—Mercury/Clark & Weinstock is pleased to announce the addition of former Congressman Denny Rehberg, public relations strategist Karen Hinton, and Democratic strategist Erick Mullen to its Washington, D.C. office. 

Denny Rehberg, Karen Hinton, and Erick Mullen are critical additions in Washington as Mercury continues to build a national, bipartisan, best-in-class consultancy.  We are thrilled they’ve agreed to join Mercury/Clark & Weinstock,” said Vin Weber, Partner and Co-Chairman of Mercury/Clark & Weinstock.

Congressman Denny Rehberg has joined Mercury/Clark & Weinstock as Co-Chairman, after serving six consecutive terms for Montana’s at-large district in the U.S. House of Representatives.  Rehberg most recently was Chairman of the Appropriations Subcommittee on Labor, Health and Human Services, Education, and Related Agencies as well as a member of the Appropriations subcommittee on Energy and Water. Chairman Rehberg was previously Lieutenant Governor of Montana, where he also served in the Assembly for three terms. 

I am excited to be joining the prestigious team at Mercury,” Rehberg said.  “This firm has a sterling reputation and a proven track-record. Mercury will afford me the opportunity to work on the issues that have defined my career and matter most to the people of Montana.”

Karen Hinton has merged her public affairs firm, Hinton Communications, with Mercury, joining MCW as a Managing Director.  Hinton, a former senior Clinton administration official, served in the Department of Housing and Urban Development under then Secretary Andrew Cuomo, in addition to her tenure in the press office at the Democratic National Committee and as press secretary to the former U.S. Congressman Mike Espy, who also served as Clinton’s Agriculture Secretary in his first term.

Mercury has the talent and experience to make a mark for its clients at a time when it’s never been more challenging to get your message out and impact policy decisions on Capitol Hill.  I’m joining a team that does more than just write a good proposal. Mercury delivers what’s in it,” said Hinton.

Erick Mullen, formerly senior staff for Senator Chuck Schumer, Minority Whip Steny Hoyer Dean of the House of Representatives, John D. Dingell, joins Mercury as a Managing Director.  In addition to a years-long tenure representing General Wesley Clark and his political action committee, WesPAC, Mullen also served as a consultant to Hillary Clinton’s U.S. Senate campaign in 2000 and Bill Bradley’s Presidential Campaign.

Joining a team that is as bipartisan in reality as it is on paper is very exciting.  Working with smart, talented people is the through-line in my career, so Mercury is the perfect fit,” said Mullen.
