Paul Ryan and Donald Trump have had a turbulent relationship throughout the course of the election.

In a last-minute campaign boost for Donald Trump, US House of Representatives Speaker Paul Ryan is back on board with the Republican presidential candidate in his bid for the White House.Ryan, a top Republican, had said in early October he would no longer campaign or defend the controversial 70-year- old real estate billionaire's comments following the leak of a 2005 video showing Trump making lewd comments about women. But yesterday, Ryan, 46, made a final case for the Republican presidential candidate.Ryan and Trump have had a turbulent relationship throughout the course of the election, but Ryan has maintained his endorsement and announced he voted for the party's nominee in Tuesday's election.Criticising Hillary Clinton, the Democratic candidate, Ryan says she has offered no new ideas to address America's biggest challenges, and that is no accident."For her, the driving force is the government -- not the individual -- and the bureaucracy is filled with unelected insiders who decide what is best for us on their whim, not our consent. It is as arrogant, condescending and paternalistic as it gets," he wrote on CNN.com."Take a look at what a unified Republican government can get you. And then vote Republican -- Donald Trump, our Senate candidates, and our House candidates -- so we can start turning things around," Ryan says."Over the last five weeks, I have traveled to nearly 25 states and more than 50 cities. I know we are ready to revitalise the American Idea, so that the condition of your birth does not determine the outcome of your life. We have a historic chance to save our country from decline and put it back on the right track. Now we have to act on it," he says."So go to better.gop and take a look at what a unified Republican government can get you. And then vote Republican -- Donald Trump, our Senate candidates and our House candidates -- so we can start turning things around."If Republicans do not turn out -- if we sit this one out -- we will open the door not just to Hillary Clinton but also a Democratic Congress eager to give her a blank cheque," he says.That's what we get if we don't win: more scandal, and more of the same. Choose a better way. Vote Republican," Ryan adds.Ryan is criss-crossing his home state of Wisconsin after having campaigned for Republicans in states across the nation to save the party's majority in Congress.Ryan, a top Republican, had said in early October he would no longer campaign or defend the controversial 70-year- old real estate billionaire's comments following the leak of a 2005 video showing Trump making lewd comments about women.
