Christopher Wray, President Trump's nominee for FBI Director, released financial records Monday that showed he is worth more than $23 million and earned $9.2 million at Atlanta-based law firm King & Spalding in 2017.

Notable clients of King & Spalding include New Jersey Gov. Chris Christie, a key early supporter of Trump's presidential campaign, as well as top state-controlled Russian oil companies.

Wray submitted an Office of Government Ethics 278 form listing dozens of investments in companies and funds amounting to up to $1 million each.

A Republican-headed Senate Judiciary Committee began confirmation hearings for Wray on Wednesday morning. If confirmed, Wray would replace James Comey, who was fired on May 9 by Trump amid an FBI investigation into former National Security Adviser Michael Flynn's connections to Russia.

Wray served in the Justice Department during the Bush era from 2001 until 2005 before returning to private practice in Atlanta as a lawyer specializing in white-collar investigations. Wray has represented clients such as Wells Fargo and Chevron, as well as online sports betting groups FanDuel and DraftKings.

His most high-profile case is representing Christie in the "Bridgegate" scandal, a federal investigation that has already resulted in the conviction of two former Christie aides for their roles in shutting down lanes on a high-traffic bridge. In Wray's financial disclosure, he listed payments he received from Christie.

During the subsequent trial, Wray made headlines when he came into possession of Christie's missing cellphone, which was sought by the lawyers of the Bridgegate defendants.

Additionally, Wray listed three "confidential clients" whose "names cannot be disclosed because they are subject to non-public investigations."

In the separate Senate questionnaire, Wray said he anticipated receiving a partnership distribution of $880,000 on July 17, adding that upon confirmation he would withdraw from the firm and recuse himself from any investigation in which his law firm represents a party, according to a CNN report.

King & Spalding has also been scrutinized for their representation of Russian interests amid allegations that the Trump campaign colluded with the Russian government during the 2016 election.

According to a Saturday report by USA Today, Wray's law firm continues to represent Rosneft and Gazprom, two of Russia’s largest state-controlled oil companies. King & Spalding's links to Russia may raise questions as to whether Wray would offer a recusal from the FBI's investigation into Russian election interference.

Rosneft was mentioned in the 35-page dossier that was prepared by former British MI6 agent Christopher Steele and released by Buzzfeed in January. The dossier claimed that Rosneft CEO Igor Sechin offered Trump campaign advisor Carter Page a 19-percent stake in the company in exchange for the U.S. lifting sanctions on Russia. The dossier claims that the offer was made in July while Page was in Moscow.
