Washington (CNN) – The White House is adjusting its security protocol to prevent uninvited guests from crashing future events, a top administration official announced Wednesday.
Going forward, White House staff will be stationed at security checkpoints alongside U.S. Secret Service agents, Deputy Chief of Staff Jim Messina said in a memo posted on the White House Web site.
"Guests will be checked off of the list by White House staff and the Secret Service will continue to ensure that all guests have been properly cleared before entering the White House," Messina wrote in the memo. "Guests whose names are not on the guest list will be assisted by White House staff present at the check point for appropriate resolution."
"As always, the Secret Service will provide security and remain ultimately responsible for controlling access to the White House complex," Messina added.
