Pelosi defends Swalwell, says Congress should fight "undue Chinese influence"

House Speaker Nancy Pelosi (D-Calif.) said Thursday she doesn't have "any concern" about Rep. Eric Swalwell (D-Calif.), after an Axios investigation revealed the congressman was targeted by a suspected Chinese spy seeking to gain access to U.S. political circles up until 2015.

Driving the news: Pelosi called for closer examination of Chinese activities "in terms of their undue influence at universities in our country and the overtures they've tried to make to members of Congress," but stopped short of saying that lawmakers should run background checks on everyone they work with.

Swalwell is not accused of wrongdoing and says he immediately cut off ties with the suspected operative, Christine Fang, when alerted by the FBI in 2015.
