“I have nothing to do with Turnberry Solutions,” he told Politico last year.

In a statement to the publication, T-Mobile confirmed that Lewandowski was involved in the negotiations, and was consulting the company on a "variety of topics."

“Corey Lewandowski is now affiliated with that firm and they have offered perspective to T-Mobile on a variety of topics, including the pending transaction,” the company said in a statement.

A lobbyist for Turnberry told Politico that Lewandowski's services to Turnberry were "unpaid," and that he had been providing "advice and counsel" to the firm "as a friend for over 20 years."

“Corey Lewandowski has never gotten any money from Turnberry Solutions,” Jason Osborne, one of Turnberry's co-founders, told Politico. “He is not a paid employee of the firm.”

Osborne, along with fellow campaign veteran Mike Rubino, had worked with Lewandowski at the lobbying firm Lewandowski started weeks after President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE won the 2016 election.

The three left the firm, Avenue Strategies, around the same time. Osborne and Rubino started Turnberry shortly after, bringing Avenue clients with them, Politico reported.

Lewandowski didn't respond to Politico's request for comment about his employment status with Turnberry or his work on the T-Mobile merger.

The former Trump campaign manager, who was fired in 2016, is now working as an adviser to Vice President Pence’s PAC, Great America Committee.

News of Lewandowski's consulting work for T-Mobile comes days after the revelation that Michael Cohen, the president's attorney, had billed himself as an insider with access to the president when advertising himself for lobbying work for firms such as AT&T.

AT&T's chief executive later issued a public apology for hiring Cohen, which he called a "mistake."
