Donald Trump has formally endorsed House Speaker Paul Ryan, after saying he wasn't ready to do so earlier this week.

Trump made the announcement during a campaign stop Friday in Green Bay, Wisconsin.

"I support and endorse our Speaker of the House Paul Ryan," Trump said, adding that while they "may disagree on a couple of things," they agree on a lot as well.

The timing is unusual. The rally is being held on a Friday night opposite the opening ceremonies of the Olympics.

In an interview earlier this week, Trump said he was "not quite there yet" when it came to endorsing Ryan in his primary race. He also praised Ryan's opponent, Paul Nehlen, for running "a very good campaign."

In addition to formally endorsing Ryan, Trump on Friday evening also threw his support behind Arizona Sen. John McCain and New Hampshire Sen. Kelly Ayotte, with whom he has sparred.

As president, Trump said he will need a Republican Senate and House to accomplish all of the changes he wants to make.

"We will have disagreements. But we will disagree as friends and never stop working together toward victory."

"We have to unite," Trump said.
