Vice President Kamala Harris’s decision to tap a high-powered lawyer representing Google in an antitrust lawsuit to help prepare for presidential debates has raised concerns from operatives on both sides of the aisle.

The Harris team added Karen Dunn as a debate preparation specialist in late July, shortly after President Joe Biden withdrew from the race, according to the Washington Post. However, the transition has raised questions of a possible conflict of interest as Dunn prepares to represent Google next month in a lawsuit brought by the Department of Justice under the Biden-Harris administration.
