Another incident with Iran is escalating tensions, the gloves are off among Democratic presidential hopefuls as they pile onto frontrunner former Vice President Joe Biden, and the first Native American poet laureate is named.
The Islamic Revolutionary Guard Corps said it shot down the American surveillance aircraft after it entered Iranian airspace.
But a U.S. official said that the drone was shot down by a surface-to-air missile in international airspace above the Strait of Hormuz.
"No U.S. drone was operating in Iranian airspace today," U.S. Central Command spokesman Capt. Bill Urban said.
The report of the downed drone comes amid rising tensions in the region, with U.S. officials blaming Iran for what they said was an attack on oil tankers in the Gulf of Oman. Iran has denied any involvement.
Recalling an era of "civility" in the Senate during the 1970s and '80s, Biden touted his experience working with two segregationist Southern senators to get "things done."
"We didn’t agree on much of anything. We got things done," the former vice president said during a fundraising event in New York City on Tuesday evening.
The comments unleashed a torrent of criticism from his Democratic rivals, some of whom denounced the comments in very personal terms by citing their own race. Sen. Cory Booker, D-N.J., called on him to apologize.
But Biden dismissed the criticism, citing his long civil rights record and standing by his comments as an example of reaching across the political aisle – even when you find your rivals personal views repugnant.

"Apologize for what? Cory should apologize," Biden said Wednesday evening. "He knows better. There's not a racist bone in my body."
