Associated Press CEO Gary Pruitt called the Justice Department's seizure of some AP telephone records "unconstitutional," saying "I really don't know what their motive was, I know what the message they are sending was - if you talk to the press we are going to go after you."

"Look, this administration says they want to be open and transparent, but they haven't," said Rep. Jason Chaffetz, R-Utah, criticizing the lack of accountability from the White House on recent controversies involving the IRS and Benghazi.

Sen. John Cornyn, R-Texas, says recent controversies over the IRS, Benghazi, and the seizure of Associated Press phone records amount to a "trend line" pointing to a "culture of cover-ups and intimidation" at the White House.
