“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.”
Brown lost reelection in 2012 to Sen. Elizabeth Warren (D-Mass.). Lieberman retired from the Senate last year after serving four terms.
