The closed-door session is expected to focus on Ohr’s relationship with Christopher Steele, the British spy behind the dossier that included salacious and unverified intelligence on Trump and Russia. It is an unlikely turn in the spotlight for the nearly 30-year veteran of the Department of Justice, who has built a reputation as the “consummate government servant” and an expert on global organized crime.

Little is known publicly about the extent of the relationship between Ohr and Steele, but some House Republicans who are vocal critics of the Russia investigation have seized on it as proof of an untoward connection between government officials and the roots of special counsel Robert Mueller’s investigation.
