WASHINGTON Homeland Security Secretary Jeh Johnson said on Monday he reassigned the acting administrator for the Transportation Security Administration after earlier ordering improved security at U.S. airports. 
 
 The moves follow media reports that checkpoint screeners failed to detect mock explosives and weapons in 95 percent of tests carried out by undercover agents. 
 
 Johnson said in a statement that Melvin Carraway would be reassigned to serve in the Office of State and Local Law Enforcement at Department of Homeland Security headquarters, while TSA Acting Deputy Director Mark Hatfield would lead the agency until a new acting administrator was appointed. 
 
 Airport screeners, who are employees of the TSA, did not detect banned weapons in 67 of 70 tests at dozens of airports, ABC News said, citing officials briefed on a report by Homeland Security's inspector general. 
 
 Johnson, whose department oversees the TSA, was briefed last week on the trials, which were completed recently, ABC News said. 
 
 In one test, the network said an undercover agent was stopped when he set off an alarm at a checkpoint but that TSA screeners then failed to find a fake explosive device taped to his back when they patted him down. 
 
 Johnson issued a statement on Monday saying the results of the security checks were classified but that he had directed the TSA to revise screening procedures "to address specific vulnerabilities identified" in the undercover operation. He also ordered training for all TSA officers and supervisors across the country and testing of airports' screening equipment. 
 
 Johnson said there would be more random covert testing at checkpoints. 
 
 "The numbers in these reports never look good out of context but they are a critical element in the continual evolution of our aviation security," Johnson said. "We take these findings very seriously in our continued effort to test, measure and enhance our capabilities and techniques as threats evolve." 
 
 Johnson noted that President Barack Obama had nominated Coast Guard Vice Admiral Pete Neffenger to be the next TSA administrator, and urged the U.S. Senate to confirm his nomination as quickly as possible.

 Homeland Security Secretary Jeh Johnson said in a statement Monday that Melvin Carraway would be moved to the Office of State and Local Law Enforcement at DHS headquarters “effective immediately.” 
 
 "I thank Melvin Carraway for his eleven years of service to TSA and his 36 years of public service," Johnson said in the statement, adding that Acting Deputy Director Mark Hatfield will lead the TSA in the interim. 
 
 Officials close to the secretary said the decision was made based on the findings in the Homeland Security Inspector General’s report, in which a series of tests were conducted by the department's Red Teams who pose as passengers. It found that TSA agents failed 67 out of 70 tests, with Red Team members repeatedly able to get potential weapons through checkpoints, according to officials briefed on the report. 
 
 In one case, agents failed to detect a fake explosive taped to an agent’s back, even after performing a pat down that was prompted after the agent set off the magnetometer alarm, according to officials briefed on the report.

 Johnson on Monday also released a six-point memo outlining actions he’s taken in wake of the security failures, including directing TSA leadership "to immediately revise its standard operating procedures for screening to address the specific vulnerabilities identified by the Inspector General’s testing."
– The TSA's acting director has been replaced by the acting deputy after an embarrassing report showed TSA agents failed 95% of tests in which fake explosives and weapons were smuggled through security. Homeland Security Secretary Jeh Johnson says Mark Hatfield will replace Melvin Carraway until the Senate can confirm President Obama's nomination of Coast Guard Vice Adm. Peter Neffenger as the agency's next administrator, which he hopes can be done "as quickly [as] possible," reports the New York Times. Carraway—who only became acting director in January, Politico notes—will move to Homeland Security's Office for State and Local Law Enforcement "effective immediately," Johnson says, per ABC News. Johnson, who thanked Carraway for his 11 years of service at the TSA, has called on the agency to retrain airport agents and supervisory personnel, retest screening equipment, and boost the number of covert tests in airports. "The numbers in these reports never look good out of context, but they are a critical element in the continual evolution of our aviation security," he says, per Reuters. "We take these findings very seriously in our continued effort to test, measure, and enhance our capabilities and techniques as threats evolve." Johnson says he will meet with companies who manufacture airport security equipment and will be given biweekly updates from officials supervising new security standards.
