Justice Rehnquist dies at home.

It looks like things are about to go into overdrive in the Senate.

U.S. Supreme Court Chief Justice William Rehnquist died on Saturday at his home in Arlington, Virginia, after battling thyroid cancer since October, a court spokeswoman said.

Rehnquist, 80, had experienced "a precipitous decline in his health in the last couple of days," and died in the evening surrounded by his three children, court spokeswoman Kathy Arberg said.
