The Senate desk that was used by Sen. Edward Kennedy -- and earlier by his brother John -- is now covered by a black shroud, and a vase of white roses.
Outside, flags are at half staff in mourning for Kennedy, who died last night at the age of 77 after a year-long struggle with brain cancer.
Officials say Kennedy will be buried at Arlington National Cemetery after a funeral mass in Boston. It's where his two slain brothers, John and Robert, are buried.
Kennedy's successor in the Senate is supposed to be chosen by special election, under Massachusetts state law. The governor says if lawmakers approve a measure allowing him to appoint a successor, he'll sign it -- but that move appears unlikely.
Meanwhile, Kennedy is being remembered as one of the most influential senators in history. President Barack Obama says his work in Congress helped give new opportunities to millions -- including Obama himself.
