Three American citizens who had been detained in China were released, a State Department spokesperson said Wednesday. They are Mark Swidan, Kai Li and John Leung.

Three Americans who had been detained in China for years have been released in a prisoner swap between Washington and Beijing.

Mark Swidan had been wrongfully detained in China since 2012, and his family fought to one day bring him home. Now, the State Department said he would return as part of a prisoner swap agreement.
