A State Department video has been altered in what could be an attempt to hide a 2013 discussion with reporters about whether the Obama administration lied about when it first began the Iran nuclear talks.

Fox News reporter James Rosen reported Monday night that a section of a Dec. 2, 2013 press briefing was somehow erased from the State Department’s own video of the event. In the section that was erased, Rosen was interviewing then-spokeswoman Jen Psaki about when the talks started.
