Dan K. Webb, a Republican, is a former U.S. attorney for Illinois and a corporate and white-collar-defense lawyer for the firm Winston and Strawn.

In a statement, his firm said the president and his team recently reached out to Webb and D.C.-based partner Tom Buchanan.

“They were unable to take on the representation due to business conflicts. However they consider the opportunity to represent the President to be the highest honor and they sincerely regret that they cannot do so,” the firm said. “They wish the president the best and believe he has excellent representation in Ty Cobb and Jay Sekulow,” referring to the two lawyers now handling Trump’s defense.
