Federal Trade Commission headquarters in Washington.

The Trump administration on Thursday formally nominated four individuals to fill vacancies on the Federal Trade Commission.

Three of the names—Joseph Simons, Noah Phillips and Rohit Chopra—were previously reported. The fourth nominee, Christine Wilson, senior vice president for regulatory and international affairs at Delta Air Lines Inc., had not been disclosed earlier.

Wilson, an antitrust and consumer protection practitioner, previously was a Kirkland & Ellis partner in Washington.

Simons, the Trump administration's pick for FTC chairman, is a top antitrust lawyer at Paul, Weiss, Rifkind, Wharton & Garrison. He had been a partner at the time President Donald Trump announced his intent to nominate him last year.

Phillips is serving as chief counsel to Sen. John Cornyn of Texas, the Republican whip. The nominee was previously a litigation associate at Cravath, Swaine & Moore in New York and Steptoe & Johnson LLP, in Washington.

In October, the Trump administration announced its “intent” to nominate Simons and Chopra, a senior fellow at the Consumer Federation of America who previously oversaw the Consumer Financial Protection Bureau's work for students.

The Trump administration did not formally send the Chopra and Simons nominations to the U.S. Senate until Thursday afternoon. The delay prompted widespread head-scratching among lawyers who practice before the FTC.
