Donald Trump has now reached the number of delegates needed to clinch the Republican nomination for president.

He was put over the top in the Associated Press delegate count by a small number of the party's unbound delegates who told the AP they would support him at the convention.

It takes 1,237 delegates to win the Republican nomination for president. Trump has reached 1,238. With 303 delegates at stake in five state primaries on June 7, Trump will easily pad his total, avoiding a contested convention in Cleveland in July.

Trump fought off 16 other Republican contenders in an often ugly primary race. Many on the right have been slow to warm to Trump. Others worry about Trump's crass personality and the lewd comments he's made about women.

But millions of grassroots activists have embraced Trump as a plain-speaking populist who is not afraid to offend.

Trump and Paul Ryan had a "good conversation" by phone Wednesday night, but the House speaker didn't offer an endorsement for his party's presumptive nominee.

Sources familiar with the call, who spoke on condition of anonymity because it was a private, called it a "good conversation" but offered few details other than saying Ryan did not endorse Trump.

The call continues the dance between Trump, who has worked for weeks to win over skeptical Republican leaders, and Ryan, who stunned many when he told CNN earlier this month he was not yet ready to endorse the presumptive nominee.

Reports surfaced earlier this week that Ryan would endorse Trump this week, but Ryan beat that back himself in a meeting with reporters Wednesday.

"I don't know where all this is coming from," Ryan said at a briefing about the House GOP's election-year agenda. "I haven't made a decision ... and nothing's changed my perspective. We're still having productive conversations."
