Donald Trump tells TODAY's Matt Lauer and Savannah Guthrie “the biggest people in the party” are already calling to sit down with him as the presumptive GOP nominee.
But Trump wouldn’t reveal which Republican leaders have reached out, aside from a phone call he said he received last week from House Speaker Paul Ryan.
"A lot of people are calling because they see what’s happening," the Republican billionaire candidate said in a phone interview Tuesday with TODAY.
Ryan spokesman Brendan Buck responded to Trump's claim by clarifying in a tweet that the "Speaker called him at his request." He also said Ryan called three other presidential candidates.
Trump said his campaign alone has attracted "millions of people" voting for the first time in the primaries and caucuses, propelling him to front-runner status.
"Those people are going to give us a tremendous victory in November," he said.
Trump finds himself ahead in polls leading into a crucial set of elections Tuesday night, with comfortable margins ahead of Ted Cruz, Marco Rubio and John Kasich. Numerous states will hold contests including Ohio, Florida, Illinois and other delegate-rich winner-take-all states.
What remains to be seen is how protests and violence at recent Trump rallies will affect his momentum in the presidential race. His rivals, both Democrats and Republicans, have taken aim at the incendiary rhetoric Trump delivers at campaign events, and one of several anti-Trump groups has begun airing an ad that has women reciting actual derogatory comments Trump has made about women.
Trump said he has not seen the ad but insisted he is leading in polls with women.
