Republicans Seek To Postpone Obama's DHS No.2 Pick's Nomination

Alejandro Mayorkas allegedly inappropriately helped a firm run by Hillary Clinton's brother

President Obama's nominee for the No. 2 spot at the Homeland Security Department ran into a wall of criticism ahead of a planned confirmation hearing late Thursday morning, as Republicans scrambled to try and postpone the hearing amid allegations he may have improperly helped a firm run by Hillary Clinton's brother. 

Alejandro Mayorkas, the director of U.S. Citizenship and Immigration Services, is under investigation by the department's inspector general. He is so far still set to testify at 11 a.m. ET before the Senate Homeland Security and Governmental Affairs Committee.
