Former Illinois Attorney General Roland Burris, nominated by Blago to succeed Obama in the Senate, is determined to take his seat in the Upper Chamber on Tuesday, despite opposition in his home state and on Capitol Hill. And he is invoking the US Constitution in his support. Burris has asked the Illinois Supreme Court to move swiftly to order Illinois Secretary of State Jesse White, who has refused to co-sign the petition from Blago appointing Burris, to approve his appointment. "Failure of this court to act very quickly would deprive [Burris] and the citizens of Illinois of the representation to which they are entitled" under the US Constitution, the motion reads. Meanwhile, the Democratic Senate leadership has made it clear Burris will not be provided with credentials to take his seat in the Senate, and may not even make it in the door of the Capitol.
