Don’t look for the White House to show up in many more Tommy Hilfiger ads. The designer is dropping its latest ad campaign after a request from 1600 Pennsylvania Avenue. One ad shows a young woman sitting on a desk in a fake Oval Office. Another has a male model standing by a helicopter next to a mock White House. White House lawyers say the request had nothing to do with the Lewinsky scandal. They say there’s a long-standing policy that the White House not be used for advertising. Some will still appear through October because it’s too late to pull them. Others, which will run into December, will have the White House cropped out.
