President Obama and first lady Michelle ObamaMichelle LeVaughn Robinson ObamaBudowsky: End the DNC malpractice George H.W. Bush in intensive care Michelle Obama congratulates duke and duchess of Cambridge on royal baby MORE attended a cocktail party Monday night at the home of NPR host Michele Norris and her husband, Broderick Johnson, an adviser to the president's reelection campaign.

The first couple spent just over an hour and a half at the reception at Johnson's Martha's Vineyard home. The Obamas are enjoying an eight-day vacation on the tony Massachusetts island.

Norris, who anchored NPR's flagship "All Things Considered" evening broadcast, stepped away from her duties in October 2011 after her husband's decision to accept a senior position with the Obama campaign.

"After careful consideration, we decided that Broderick's new role could make it difficult for me to continue hosting ATC," Norris said in a statement.

"This has all happened very quickly, but working closely with NPR management, we've been able to make a plan that serves the show, honors the integrity of our news organization and is best for me professionally and personally."

Norris rejoined the network 15 months later but did not return to the daily news program, instead serving now as a guest host and special correspondent.

Johnson's involvement in the campaign was itself controversial. Before founding his own communications firm, he worked for the lobbying firm Bryan Cave LLP on behalf of clients that included Microsoft, Comcast, and TransCanada — the company hoping to build the Keystone XL pipeline.

Environmental activists have complained that the pipeline would increase greenhouse gas emissions and endanger an aquifer that serves as the primary source of drinking and irrigation water to the High Plains states.
