Steve Bannon, the former White House chief strategist, has hired a lawyer as he prepares to appear before the House Intelligence Committee as part of its investigation into Russian meddling in the 2016 election, according to a report.

Bannon hired Bill Burck, a co-managing partner of Quinn Emanuel Urquhart & Sullivan LLP’s Washington, D.C., office, according to The Daily Beast.

White House counsel Don McGahn and former White House chief of staff Reince Priebus hired Burck in September to represent them in special counsel Robert Mueller’s investigation into Russian meddling and possible collusion between the Trump campaign and Russia.

Bannon is scheduled to testify before the House Intelligence Committee next week. Sources told The Daily Beast the former chief strategist intends to “fully cooperate.”

Bannon was hired as chief executive of the Trump campaign in August 2016 and was tapped by President Trump to serve as White House chief strategist. He left his post there in August 2017 and returned to Breitbart News as its executive chairman.

But, Bannon and Breitbart parted ways earlier this week amid a spat between President Trump and his former chief strategist. Bannon made derogatory comments about the president and his family in a new tell-all book, prompting a fiery condemnation from Trump.

Though Bannon had previously avoided being swept up in the Russia probe—until the House Intelligence Committee asked last month for him to appear before lawmakers—he had been discussing the probe with Trump behind the scenes.
