Donald Trump has endorsed the US House of Representatives Speaker Paul Ryan, having earlier publically snubbed him.
The US Republican presidential candidate had previously refused to endorse Mr Ryan and the change of hear appears to be an attempt to reclaim lost ground with the party establishment.
"I support and endorse ... Paul Ryan," Mr Trump said during a rally in Green Bay, in northern Wisconsin, Ryan's home state.
"I need a Republican Senate and a House to accomplish all of the changes that we have to make."
He also endorsed Senators John McCain of Arizona and Kelly Ayotte of New Hampshire, both of whom he had previously been cool towards.
Mr Ryan is the highest-ranking elected Republican.
Earlier in the week, Mr Trump told The Washington Post he was not endorsing Mr Ryan because he was "not quite there yet", the same phrase Mr Ryan had used about Trump before finally endorsing him.
Also at the rally, Mr Trump reiterated his charge that Clinton is the "queen of corruption" and defended himself against her charge that he is temperamentally unfit for the White House.
He also defended himself against what he called the news media's claim that he kicked a baby out of an event earlier this week in Virginia. "I love babies," he told the crowd.
