copyright 2009, The Washington Post WASHINGTON -- Swapping senior administration officials in midstream is often difficult. The incoming boss generally doesn't have the luxury of assembling 'his' team. Fortunately for Bob Bauer, the incoming White House counsel, at least there's one top opening available for him to fill -- the job of deputy counsel, most recently held by Obama Harvard Law School pal and inner-circle member Cassandra Butts. Butts had been talked about in March to head the especially troubled Equal Employment Opportunity Commission, but she opted not to test the culinary delights of the Wendy's and other fast-food joints near the agency's new headquarters near New York Avenue NE. Butts instead was named Nov. 6 to be senior adviser in the Office of the Chief Executive Officer at the Millennium Challenge Corp., the international aid organization set up during the Bush administration to focus aid on countries whose governments are committed to democracy and economic freedom and so forth. The MCC is also just a few blocks from the White House.
