Trump's takeover of the GOP, one year later

Wednesday marks the one-year anniversary of Donald Trump winning the Indiana primary, knocking off the last of his competitors for the Republican nomination and setting himself on a path to the presidency of the United States.

"It has been some unbelievable day and evening and year — never been through anything like this," Trump declared in his victory speech, calling it a "beautiful thing to behold." Then-Republican National Committee Chairman Reince Priebus said on Twitter that Trump would be the "presumptive nominee," and called on the party to "unite and focus on defeating" Hillary Clinton.

Now Priebus is the White House chief of staff under President Trump and one of his RNC deputies, Sean Spicer, is the White House press secretary. Mike Pence, the governor of Indiana who endorsed Ted Cruz as part of the Never Trump conservatives' last stand, is vice president.

Many Republicans who had been far more critical of Trump now work for him. Education Secretary Betsy DeVos never endorsed him during the campaign. United Nations Ambassador Nikki Haley and White House budget director Mick Mulvaney were much more enthusiastic supporters of Trump primary opponents.

House Speaker Paul Ryan, R-Wis., was one of the last holdouts among national GOP leaders who didn't immediately endorse Trump after Indiana. Ryan has ended up working closely with Trump on a shared Republican agenda.
