CREDIT: AP The White House is denying an Israeli news network’s report that Valerie Jarrett, one of President Barack Obama’s top advisors, has been secretly conducting negotiations with Iran for more than a year, attempting to stifle rumors that have been granted new life after circulating since last fall. Israel’s Channel 10′s report aired Sunday, which cites several unnamed “senior Israeli officials,” claiming that Jarrett has been holding talks with Iran over its nuclear program in backrooms for the last year, and keeping Israel in the dark.
