Republican Donald Trump took steps to steer his White House campaign back into favor with his party establishment on Friday by endorsing House of Representatives Speaker Paul Ryan and two Republican senators seeking re-election, after expressing coolness toward them earlier in the week.

"I need a Republican Senate and a House to accomplish all of the changes that we have to make," Trump said during a rally in Green Bay, in northern Wisconsin, Ryan's home state. He also endorsed Sens. John McCain of Arizona and Kelly Ayotte of New Hampshire, whom he called a "rising star."

"We will have disagreements, but we will disagree as friends," Trump said.
