David Axelrod claimed Wednesday that when he served in the Obama administration, he was unaware that former Secretary of State Hillary Clinton used an unauthorized, private server.

"I was there, I was the senior adviser. I didn't know that," Axelrod said on MSNBC's "Morning Joe."

Had he known, he would have asked some questions. "I might have asked a few questions about [the private server]," he said.

He was quick to add, though, that voters likely won't care about this and will focus on other areas as the 2016 presidential election nears.

"Morning Joe"'s Mika Brzezinski suggested that Axelrod would have likely done something more than asked questions had he known about Clinton's "home brew" server.

"I would ask a question," he responded. "If the St. Louis Cardinals can poach the secrets of the Houston Astros, then it speaks to the age in which we live, so I would have concerns about it."

Axelrod served as President Obama's senior advisor from 2009 to 2011. He left his position in the White House to help re-elect the president in 2012.

Clinton worked at the State Department from 2009 to 2013. During her entire time at Foggy Bottom, she never once sent an official email bearing the standard @state.gov address.

Instead, she used several personalized email addresses, including hdr22@clintonemail.com and hrod17@clintonemail.com.

Reports that Clinton used a private and likely insecure "home brew" server surfaced in March after the New York Times caught wind of the story.
