Sen. Tom Carper led a group of senators in writing to FBI Director Christopher Wray to request information regarding the extent to which President Donald Trump and the White House were involved in the abrupt decision to reverse course on plans for the FBI headquarters project and whether that involvement was appropriate.

The senators requested emails, correspondence, memos, notes, comments, papers, faxes, photographs and text messages related to the decision-making process.

This request followed an investigation led by the General Services Administration inspector general, which included a review of GSA’s decision-making process regarding the revised plan for the FBI headquarters project. That investigation revealed potentially inappropriate involvement by the White House and that GSA Administrator Emily Murphy may have misled Congress about White House involvement in the project.

The letter is signed by Sens. Carper, D-Delaware; Ben Cardin, D-Maryland; Sheldon Whitehouse, D-Rhode Island; Mark Warner, D-Virginia; Tim Kaine, D-Virginia; and Chris Van Hollen, D-Maryland.
