US president-elect Barack Obama resigned his seat in the Senate yesterday and thanked his home state of Illinois for launching his political career.
"Today, I am ending one journey to begin another," Mr Obama said in a letter to the people of Illinois, describing his job representing them as one of the highest honors of his life.
"I am stepping down as senator to prepare for the responsibilities I will assume as our nation's next president," he said. "But I will never forget, and will forever be grateful to, the men and women of this great state who made my life in public service possible."
Mr Obama's resignation as senator means he will not participate in this week's post-election session on Capitol Hill that could address the ailing economy and struggling auto industry.
His successor in the Senate will be appointed by Illinois Governor Rod Blagojevich, a Democrat.
Mr Obama cited one of his heroes, Abraham Lincoln, who hailed from the same state, when saying his goodbye.
"It was long ago that another son of Illinois left for Washington," Obama wrote. "A greater man who spoke to a nation far more divided, Abraham Lincoln, said of his home, 'To this place, and the kindness of these people, I owe everything.' Today, I feel the same."
The Democratic president-elect has been assembling his White House team and studying cabinet appointments since beating Republican rival John McCain in the November 4th election.
The president-elect added three officials to his White House team yesterday, making his top aide from the Senate a senior adviser and naming two deputies to chief of staff Rahm Emanuel.
Mr McCain will visit Mr Obama in Chicago on Monday to discuss ways the two men can work together.
