The Latest on Ohio voting and election issues (all times local):
Ohio's elections chief says voting in the swing state went smoothly and turnout was robust.
Republican Secretary of State Jon Husted (HYOO'-sted) told reporters Tuesday in Columbus that concerns over voter intimidation at the polls never materialized on Election Day. He thanked poll workers and voters for being "on their best behavior."
Republican presidential candidate Donald Trump had called on supporters to watch for fraud at the polls. That stirred fears of minority voters being confronted and challenged by self-appointed poll watchers.
Husted said he believed such intimidation fears were exaggerated because there was no evidence that it was going to happen. He says Ohio was prepared for intimidation reports.
Ohioans cast ballots for the presidential election, a U.S. Senate race, congressional and state legislative races and local school issues.
Former Ohio Democratic Gov. Ted Strickland has conceded the U.S. Senate race to Republican incumbent Rob Portman.
Minutes after The Associated Press projected that Portman had won a second term, Strickland issued a statement saying he called Portman to congratulate him and wish him well.
Strickland says the result wasn't what he hoped for, but he is grateful to have had the opportunity to speak out for hardworking Ohioans.
Portman plans to make a victory speech at 8:20 p.m.
They had served together in Congress, representing southern Ohio districts. Strickland was defeated for re-election as governor in 2010 by Gov. John Kasich (KAY'-sik) as Portman handily won his first term.
Ohio Republican U.S. Sen. Rob Portman has won re-election over Democratic former Gov. Ted Strickland in a race Democrats once considered a good opportunity to pick up a Senate seat.
Portman ran a savvy and well-funded campaign that kept Strickland on the defensive and kept Republican presidential nominee Donald Trump at a distance leading up to Tuesday's election.
Portman's campaign branded Strickland "Retread Ted" and highlighted Ohio's economic struggles, which saw 350,000 jobs lost during Strickland's governorship. Strickland blamed the Great Recession and said he had started the state's recovery.
Portman didn't campaign with Trump and withdrew his endorsement of him when a 2005 tape of Trump making lewd comments about kissing and groping women surfaced weeks ago.
Portman served in the administrations of Republican former Presidents George H.W. Bush and George W. Bush.

A Columbus Republican who describes himself as a conservative said he voted for Trump on Tuesday as someone who could get things done. Carl Cray said he supports Trump's proposal to build a wall along the border with Mexico. The 62-year-old retired newspaper press operator said change is needed in Washington.
Registered independent Michael Emmerich voted Tuesday in suburban Cleveland for Democrat Hillary Clinton. The 45-year-old commercial pilot said his vote was mostly against Trump because he prefers the status quo to the kind of change Trump would bring.
Emmerich said the Republican candidate is "completely unqualified" to lead the country.
The state's elections office says Tuesday turnout appears to be robust across Ohio with relatively few problems.

McClellan says county election boards have troubleshooters lined up in case of any issues during the day.
