Supreme Court Justice John Paul Stevens is expected to announce his retirement in April.
Stevens told a CNN analyist on March 8 that he would decide if he would retire in about a month, CNN reported.
Another hint that Stevens will retire was fall hiring of one law clerk, when four are normal, CNN said. Retiring justices are only allowed one law clerk.
Democratic leaders hope that Stevens will remain a justice for another year to avoid a Republican filibuster of the nomination in response to their dissatisfaction with the recent health care bill, the Wall Street Journal reported.
Stevens is known for his liberal politics, and the Democratic influence in the Supreme Court will likely diminish when a replacement is selected, the Wall Street Journal said.
