Trump scorns Republican opponents as well as Democrats

WASHINGTON (AP) — Presumptive Republican presidential nominee Donald Trump's derision of his political opponents draws hearty boos of support at rallies.

Appearing at rallies Friday in Nebraska and then Oregon, Trump repeated his nickname for Democratic front-runner Hillary Clinton — "crooked Hillary" — but stepped up his attacks on Clinton by referencing her husband's infidelities for the first time since he became his party's presumptive nominee while dismissing her criticism of how he treated women.

Warren, a favorite of the Democratic left whom some would like to see as Clinton's running mate, had insulted Trump earlier on Twitter, calling him "a bully who has a single play in his playbook."

"The thing that matters most are the millions of people that have come out to vote for me and give me a landslide victory in almost every state," Trump said moments after Ryan announced their planned meeting.

The telegenic Wisconsin Republican served as his party's vice presidential nominee in 2012, was drafted to the high-profile role of House speaker last fall and is seen as having designs on the 2020 presidential nomination himself.

[...] that runs the risk of creating a Goldwater kind of moment where the party really does split, former House Speaker Newt Gingrich told The Associated Press, referring to the 1964 Republican presidential nominee whose candidacy divided the GOP and was followed by a big Democratic victory.
