Question: (CNN) -- A former security guard told CNN on Monday that he was unjustly fired after he took pictures of President Barack Obama's motorcade during a visit to Atlanta in September. Kenneth Tate worked for a private security firm when President Obama visited the Centers for Disease Control and Prevention on September 16. He told CNN's Brooke Baldwin in an exclusive television interview that he stuck to his assigned duties and tried to take photos after he was done escorting President Obama. Members of Congress were upset when the media reported last month that Tate had a .40-caliber handgun while in an elevator with the President. That report, coupled with news of an incident in which a man jumped a fence and made it into the White House, led to the resignation of Secret Service Director Julia Pierson.Fired security guard tells CNN he stuck to his assigned dutiesKenneth Tate only went to take pictures when the detail was over, he saysFederal official says CDC asked for Tate to be reassignedTate says he carried a handgun that he was given, never took photos of President on elevator

Question: An unusual nexus of mining interests, relief work in Haiti, and a former U.S. first family is raising new ethics questions that could affect Hillary Clinton's presidential ambitions. Clinton's brother, Tony Rodham, was a board member of a North Carolina mining company that enjoyed prime access to Haitian gold deposits in the wake of post-earthquake relief work organized in part by former president Bill Clinton through the Clinton Foundation. Another board member of the firm, VCS Mining, was former Haitian Prime Minister Jean-Max Bellerive, who co-chaired the charitable Interim Haiti Recovery Commission with Mr. Clinton. The revelation, smacking of cronyism and back-room government dealing, is part of a forthcoming book by Government Accountability Institute founder Peter Schweizer, whose work exposing the investment 'insider trading' habits of members of Congress caused national outrage in 2011 even though the practice was legal.Book due out in May describes alleged sweetheart deal that netted VCS Mining a gold concession that hadn't been issued to anyone in 50 yearsTony Rodham, Mrs. Clinton's brother, sat on the company's boardAnother board member co-chaired a relief effort with former President Bill Clinton following a devastating 2010 earthquake'Clinton Cash' is the latest from Peter Schweizer, who turned heads in 2011 with an expose about insider trading by members of Congress
