President Biden on Sunday called for the release of American hostage Mark Frerichs ahead of the two-year anniversary of his abduction if the Taliban expects to be recognized as the legitimate government of Afghanistan. "Two years ago tomorrow, U.S. Navy veteran Mark Frerichs was taken hostage in Afghanistan. A civil engineer, he spent a decade helping the people of Afghanistan. He has done nothing wrong. And yet, for two years the Taliban has held him captive," Biden said in a statement.
