Back in Washington, former Food and Drug Administration head Lester Crawford pleaded guilty Tuesday to conflict of interest and false reporting of ownership of stock. Crawford stepped down as President Bush’s FDA Commissioner just over a year ago. Prosecutors say he lied about stock in several companies regulated by the agency. Two of the companies — PepsiCo and Sysco — were directly involved in hearings that Crawford oversaw. Crawford faces a maximum two years in prison and a $200,000 fine.
