The American Center for Law and Justice sued the Justice Department on Wednesday to obtain more information about Attorney General Loretta Lynch's June meeting with former President Bill Clinton on the tarmac at an Arizona airport days before her agency dropped its investigation into Hillary Clinton's private email use.

"This Administration has gone out of its way to hide information from the American public — information that is extremely troubling," Jay Sekulow, the ACLJ's chief counsel said in announcing the lawsuit under the Freedom of Information Act.

"The stakes are high," he added. "The American people deserve a Justice Department with integrity."

Lynch and Bill Clinton met June 27 aboard Lynch's private jet at Phoenix Sky Harbor International Airport. Clinton had delayed the departure of his flight in order to meet with Lynch.

On July 7, Lynch accepted the findings of FBI Director James Comey just two days prior.

While Comey said Clinton and her aides were "extremely careless in their handling of very sensitive, highly classified information,” he said he was not recommending charges in the case.

Lynch's move effectively closed the investigation.

However, Comey told Congress last Friday he was probing emails had recently been discovered on a laptop shared by longtime Clinton aide Huma Abedin and her estranged husband, Anthony Weiner.

The attorney general had insisted her meeting with Bill Clinton was social, but Republicans have long charged the session led to Lynch's decision to drop the probe.

"She has no business having any involvement in an FBI investigation of this magnitude," Sekulow said Wednesday.

In its FOIA lawsuit, the ACLJ is seeking all messages Lynch or her subordinates might have reviewed mentioning the tarmac meeting, names of Justice Department workers who might have discussed the meeting — as well as documents detailing conversations about news organizations regarding the fallout.
