WASHINGTON — President Trump’s nominee to lead the Justice Department’s criminal division, Brian A. Benczkowski, has disclosed to Congress that he previously represented Alfa Bank, one of Russia’s largest financial institutions, whose owners have ties to President Vladimir V. Putin.
Mr. Trump nominated Mr. Benczkowski, a partner at the Kirkland & Ellis law firm and a former Bush administration Justice Department official, in June, and he is scheduled to appear before the Senate Judiciary Committee for a confirmation hearing on Tuesday.
Alfa Bank was at the center of scrutiny last year over potential ties between the Trump campaign and Russia after computer experts discovered data suggesting a stream of communications between a server linked to the Trump Organization and a server linked to the bank. Reports about the mysterious data transmissions fueled speculation about a back channel.
The F.B.I. investigated the matter, however, and concluded that the servers’ interactions were not surreptitious exchanges between the campaign and Russia, according to current and former law enforcement officials. Experts have argued that the server linked to the Trump Organization appeared to be controlled by a marketing firm, Cendyn, that was sending emails promoting Trump hotel properties.
