Republican Rep. Jason Chaffetz of Utah, chair of the House Oversight and Government Reform subcommittee on national security, told The Hill he met with the victims' families and is poised to send questions to the Pentagon.
"We're going to dive into this," Chaffetz said, adding that his subcommittee may hold hearings.
SEAL Team 6 members were among 30 American service personnel who died August 6, 2011 when their chopper went down shortly after taking off on a rescue mission.
The crash occurred just three months after Osama bin Laden was killed in Pakistan by Team 6 members. It represented the largest death toll of any single incident for the U.S. military during the Afghan war.
Documents provided to the victims' families indicate the Pentagon doesn't believe the SEALs were targeted.
Charles Strange, whose son Michael was among those who died, said insurgents were boasting on the Internet that they had taken out SEAL Team 6 shortly after the CH-47 Chinook crashed.
Strange said President Obama promised he would investigate but Strange never heard back from the White House.
He said the Pentagon has provided the families of victims with incomplete and contradictory information.
"This is a scandal even greater than Benghazi," said Larry Klayman of Freedom Watch. "There we lost four valued American lives; here we sacrificed 30 American soldiers."
