Nellie Ohr, the wife of Justice Department official Bruce Ohr, is under scrutiny again.

GOP lawmakers in the House seek Ohr's opposition research on members of the Trump family, according to Fox News.

In testimony to lawmakers late last year, Ohr said she gathered information during the 2016 campaign about President Trump, his wife Melania Trump, and his children for Fusion GPS, the same opposition research firm that was paid by the Democratic National Committee and the Hillary Clinton campaign for British ex-spy Christopher Steele's anti-Trump dossier.

The Republican investigators want to know if Ohr's Trump family research made it to the FBI or got into Steele's dossier.

Ohr testified in December that she was tasked with researching the Trump family "broadly in connection with any – any Russian connections." She said she investigated family members' foreign travel, but claimed her research lacked "depth," and claimed her goal was to "see whether they were involved in dealings and transactions with people who had suspicious pasts, or suspicious types of dealings.”

At the time, Ohr said she was still in possession of her research and indicated she might be willing to share it with the committee. Fox News reached out to her lawyer with questions about the records, including whether the documents require a subpoena. A response has not yet been published.

Ohr's husband Bruce is believed to have acted as an unofficial back channel between the FBI and Steele. He was demoted when it was revealed he met with Steele and Glenn Simpson, the co-founder of Fusion GPS. Steele's dossier, which contained unverified claims about Trump's ties to Russia, has been a subject of concern for GOP lawmakers, particularly for how it was used by the FBI in Foreign Intelligence Surveillance Act warrant applications to gain the authority to spy on onetime Trump campaign adviser Carter Page.

Both Ohrs testified last year to a joint task force of the House Oversight and Judiciary committees that were investigating decisions made by the Justice Department and FBI surrounding the 2016 election.

In his congressional testimony, Bruce Ohr also told lawmakers his wife shared a thumb drive with him to hand over to the FBI.

Nellie Ohr also testified that she met with Steele the day before the FBI launched its Trump-Russia investigation at a hotel in Washington, D.C.

Rep. Mark Meadows, a Republican from North Carolina, sent a criminal referral addressed to Attorney General William Barr earlier this year, citing concerns that Nellie Ohr "knowingly provided false testimony" to lawmakers.

Barr is overseeing a review, led by U.S. Attorney John Durham, of the origins of the Russia investigation.
