SCROLL DOWN FOR VIDEO . This screen grab from a police video shows a March 4 , 2015 incident involving allegedly drunk Secret Service agents who hit a White House barricade while a suspicious package was under investigation nearby . NUDGED IT THIS MUCH : Secret Service Director Joseph Clancy testified before the House Oversight and Government Reform Committee , the third such grilling he 's endured in the last week . ANONYMOUS EMAIL : The House Oversight Committee heard testimony about how Clancy learned about the incident – after this message had already circulated among agents for several days . Clancy has been criticized for the agency 's handling of the incident . He has said he was out of the loop in the days that followed . 'The fact that I did not learn about this allegation until five days [ afterward ] ... infuriates me , ' he told the congressional panel . 'This is unacceptable . Our mission is too important for this to happen . It undermines my leadership . ' He said he only learned about the incident from discussions about an anonymous email that was circulating within the agency . The email described the off-duty agents as 'both extremely intoxicated ' and confused about the bomb investigation underway near where their vehicle came to rest . It said uniformed Secret Service officers at the scene 'were going to arrest both of them , but the UD ( Uniform Division ) watch commander said not to . ' ' A liot of people got this email , ' fumed Maryland Rep. Elijah Cummings , the oversight committee 's ranking Democrat . ' A lot of them got it , ' he blared at Clancy , but you did n't ! ' Utah Republican Rep. Jason Chaffetz , the committee 's chairman , angrily recounted a series of events including an 11-minutes stretch of time the Secret Service let the suspicious package lay near the White House before evacuating the area . ' I don ’ t understand how that happens , ' he said . DC Metropolitan Police video shows a car delivering a suspicious package to the White House perimeter ; the woman driving claimed it contained a bomb . Minutes later an SUV driven by an agent who had been drinkign at a retirement party drove into a Secret Service barricade near the scene of the 'bomb ' investigation . Clancy , a former top agent on President Obama 's protective detail , came out of retirement to lead the Secret Service after a series of scandals forced out his predecessor , Julia Pierson . The March 4 debacle was part of ' a litany of recent mishaps , ' Chaffet lectured , which 'raise major concerns ' about the Secret Service 's ability to protect the presidential mansion and the first family . 'This has to stop , ' he said . 'We need to understand why these incidents keep happening . ' The Homeland Security Department 's inspector general is investigating allegations against the agents . Lawmakers asked to speak with the agents involved , as well as Secret Service supervisors who were on duty that night , during the hearing . The Secret Service declined to make them available and Clancy appeared alone . In a written statement , Clancy said the case remains under investigation and any appropriate discipline will be imposed afterward . Clancy also announced a new policy put in place after acknowledging that some video of the March 4 incident had been deleted . The video was shown to a crowded hearing room on Capitol Hill as a helpless Clancy watched . Ultimately the Secret Service agents on duty determined that the package was n't dangerous – but the agents in the SUV could n't have known that . Clancy said the agency will start retaining routine surveillance video for seven days . Previously , surveillance recordings that were n't being used as part of ongoing investigations were deleted after 72 hours . Chaffetz said it was 'highly suspicious ' the video was deleted . 'We asked Director Clancy to turn over video footage of the incident . He said no , ' Chaffetz fumed on Tuesday .
