WASHINGTON: An apparent chance meeting between former president Bill Clinton and US Attorney General Loretta Lynch made waves Thursday in Washington, as White House hopeful Hillary Clinton’s email usage remained under investigation. The Monday meeting came a day before Republican lawmakers released their final report on the 2012 assault on the US mission in Benghazi, and as Hillary Clinton’s campaign faces continued questions about her trustworthiness. The encounter raised concern about whether the independence of the Department of Justice, which is led by Lynch and is conducting an investigation into the emails, has been compromised. Lynch said the meeting at the airport in Phoenix, Arizona was purely coincidental and stressed that the conversation did not touch on any cases for which her office is responsible. “There was no discussion of any matter pending for the department or any matter pending for any other body,” she said, according to US media. “There was no discussion of Benghazi, no discussion of the State Department emails, by way of example.” Clinton’s use of a private email account and home server while secretary of state between 2009 and 2013 has weighed on her campaign for a year and served as a preferred line of attack by her political opponents.
