WASHINGTON (AP) -- Senate Democratic Leader Harry Reid, the wily Nevadan who dominated the Senate for a decade from the minority to the majority and back again, announced Friday he will retire after five terms.

Three-term New York Sen. Chuck Schumer faces a relatively clear path to replace him as the next Democratic leader. Reid endorsed the No. 3 Senate Democrat, and Dick Durbin of Illinois, the current No. 2, told Schumer Thursday night he had his support, according to a spokesman.

Durbin plans to run again for the job of Democratic whip.

"I think it's very important to have continuity in our leadership," Reid told KNPR radio in Nevada about backing Schumer.

Reid, 75, who shepherded key Obama administration initiatives including the president's health care law, lost his role as majority leader - the Senate's top job - when November's elections swept the Republicans into control. He suffered a personal setback on New Year's Day, falling while exercising and suffering serious bruises and a lasting injury to his right eye.

Reid was the Republicans' top target in 2016 and widely considered vulnerable to losing the seat he'd held since 1987.

Still, the stubborn gold miner's son had cheated political death before, and few were writing him off.

In a statement early Friday, Reid said the recovery period from his eye injury, which may leave him with permanent vision loss, gave him time to think about his political future.

"We have to make sure that the Democrats take control of the Senate again," he said. "And I feel it is inappropriate for me to soak up all those resources on me when I could be devoting those resources to the caucus, and that's what I intend to do."

Reid, who rose from nothing in the tiny desert town of Searchlight, Nevada, had grown more unpopular at home due to positions he'd taken on national issues. He turned back a challenge in 2010 and was sure to face an aggressive, big-money attack by Republicans if he ran again.

President Barack Obama issued a statement that said Reid "has become not only an ally, but a friend."

In a surprise, Obama called in to the radio show, chatting with Reid about their years together pushing legislation, fighting the Great Recession and overhauling the nation's health care system.

Said Obama, "We've had a great run."

As Democratic leader, Reid thrived on behind-the-scenes wrangling. He guided the Senate through a crippling recession and the GOP takeover of the House in the 2010 elections, which sparked years of bitter partisan battles and congressional gridlock.

He was known for frequent gaffes and impolitic remarks, once complaining that tourists to the Capitol smelled, and calling former President George W. Bush a "loser" and a "liar."

Since returning to work after his fall, Reid has struggled to regain sight in his right eye, appearing in the Capitol in bandages and then with his eye shielded by tinted glasses. He told The Associated Press early this month that the injury was "a tremendous inconvenience," but nothing more, and not enough to stop him from seeking re-election.

"I've had black eyes before," said Reid, who was an accomplished amateur boxer in his youth.

Even from his post in the minority, Reid leveraged Senate rules to exert steely control. He held his 46-member caucus together against attempts by Republicans to pass legislation undoing Obama's executive actions on immigration, forcing Senate Majority Leader Mitch McConnell to back down, and House Speaker John Boehner to follow. The episode left some House Republicans complaining bitterly that Reid might as well still be majority leader.

In classic fashion, Reid could not resist needling McConnell, with whom he had an icy relationship, as he disclosed his departure.

"My friend Sen. McConnell, don't be too elated. I'm going to be here for 22 months," Reid said in a video he filmed to announce his retirement.

McConnell was gracious in his comments on Reid's retirement.

"Nothing has ever come easily to this son of Searchlight," the GOP senator said in a statement. "Underestimated often, his distinctive grit and determined focus nevertheless saw him through many challenges. They continue to make him a formidable opponent today."

Reid insisted that his decision had nothing to do with his injury or his re-election chances, saying "the path to re-election is much easier than it probably has been anytime that I've run for re-election."
