Joe Lieberman, Scott Brown join national security group

BCAS is a 501(c)4 nonprofit, which means it is a “social welfare” group under the tax code. They are able to participate in political elections, including collecting anonymous donations to run ads for or against candidates, as long as that is not their primary purpose.

“We increasingly face the danger of a new consensus in Washington that favors retrenchment and disengagement from challenges overseas, and that downplays the dangers we face as a nation,” Lieberman said in a statement. 

The group’s advisory board has not been fully announced, except for venture capitalist and Los Angeles-based philanthropist Elliott Broidy, who was appointed to the White House’s Homeland Security Council from 2005 to 2009 and also worked on the Department of Homeland Security’s Future of Terrorism Task Force and the New Technology Task Force.

The organization’s goals include ensuring “robust” funding for national security programs, including defense, intelligence and foreign aid, according to its website.

“Many serious issues that affect the security and interests of the United States often culminate outside our boarders long before they reach our shores and become a danger to America,” Brown said in a statement. “In order to properly thwart those threats and deal with the agenda of our enemies, we must maintain effective global outreach efforts and deliver strong support for our allies and friendly nations around the world.”

Brown also emphasized working on bipartisan solutions.

“As a nation we cannot afford to shift our national and global security resources and policies from being expansive and focused on global stability, to one centered on protectionism,” Brown said. "The stakes for America abroad have never been higher or more important than they are today.”
