WHITE HOUSE . . . STIRRED, NOT SHAKEN

Now that he's fulfilled his golfing quota, President Clinton is considering in earnest some staff changes recommended by his new White House-cleaning chief of staff, Leon Panetta. While Clinton isn't expected to issue major announcements this week, he's approved stricter job definitions for free-floating senior aides, who can no longer saunter into the Oval Office at will. As of today, ex-communications director George Stephanopoulos is Panetta's deputy; adviser Bruce Lindsey moves to the White House counsel's office, as does Clinton kindergarten buddy and Panetta predecessor Mack McLarty. Next week's predicted reassignment: axing or reassigning press secretary Dee Dee Myers.
