George Stephanopoulos gives some background about his interview with Iranian President Mahmoud Ahmadinejad on his blog today.

"After the 'This Week' show on Sunday — and after five years of requests — I received word from the Iranian interests section that President Mahmoud Ahmadinejad had agreed to an interview with me," he wrote. "But there was a catch: I had to be there by Wednesday at the latest."

Stephanopoulos made it, and what transpired were "some spirited exchanges, as you might imagine, on the nuclear talks, the Holocaust, and who's really to blame for the breakdown in U.S.-Iran relations."

He also asked to see jailed journalist Roxana Saberi. Said Ahmadinejad: "Let's see if our judiciary allows for that, sure. But if they do not allow for that, no. I am afraid not."

The ABC anchor was not allowed, but he did visit Saberi's parents, who told him she will begin a hunger strike tomorrow.
