Scott Powers, a reporter with the Orlando Sentinel, was relegated to the storage space during a fundraiser Wednesday for Sen. Bill Nelson, D-Fla., apparently to prevent him from speaking to people before Vice President Biden showed up. The Orlando Sentinel published a brief account of the incident earlier in the week.

Biden spokeswoman Elizabeth Alexander, responding to coverage of that account, said in a written statement Sunday that the decision to hold Powers there was a “mistake” and that the reporter has accepted her “unequivocal apology.” The apology was made shortly after the fundraiser.

“This was the unfortunate mistake of an inexperienced staffer and the vice president’s office has made sure it will never happen again,” she said.
