The Federal Bureau of Investigation will face a congressional subpoena as part of an effort to better understand its connections to the owner of a stretch limousine that crashed in 2018 and killed 20 people, Rep. Elise Stefanik said Tuesday. 

Stefanik has signaled over the last year a Republican majority would seek more information from the FBI on Shahed Hussain, who had run a limo rental business and had been an undercover informant for the bureau. 

On Tuesday, Stefanik in a statement said subpoena power will be wielded by House Republicans if the information isn't made available to lawmakers. 

"Make no mistake, House Republicans will have control of the gavels next Congress, and the FBI can expect rigorous oversight next year for their involvement in the most deadly transportation disaster in decades to get answers for these families," Stefanik said. "The subpoenas are coming.”

Stefanik in March had asked FBI Director Christopher Wray about the bureau's interactions with Hussain and whether he was aware of the allegations facing his limousine company. Wray declined to comment, citing concerns over confidential sources. 

In a subsequent follow up letter, Stefanik knocked the FBI for failing to release more information. 

“The FBI is completely failing their responsibility to inform Congress, and they can no longer brush off my requests on behalf of New York families,” she said in Tuesday's statement. 

Shahed Hussain son, Nauman, has been the only person charged in the crash, considered the deadliest transportation disaster in a decade.

Nauman Hussain had initially entered a guilty plea in the cash that would have required community service, but resulted in no prison time. But in August, a judge rejected the agreement calling it "fundamentally flawed." 

The development is now being fought over in a court challenge.  

Stefanik has previously vowed to use congressional subpoena authority to investigate former Gov. Andrew Cuomo's handling of nursing homes during the initial weeks of the COVID pandemic.
