Reince Priebus (ryns PREE'-bus) tells CBS' "Face the Nation" that voter fraud is not "some figment of people's imagination." He says Trump merely wants his supporters to "watch out for voter fraud that might occur." Priebus says Trump is referring to narrow scenarios in which only a few hundred votes separate the candidates.

Priebus says he expects Trump to win the election, and predicts he will do better in African American communities than Republicans did in the previous two presidential elections.

NEW: Clinton campaign calls inciting violence unacceptable

WASHINGTON (AP) — Hillary Clinton's campaign manager Robby Mook says it's "unacceptable" for anyone in either party to incite violence as part of a political campaign.

Mook is referring to secretly recorded video footage released by conservative activist James O'Keefe. It shows a Democratic activist bragging about deploying troublemakers at rallies held by Donald Trump.

Mook tells CNN's "State of the Union" that the activists in the video "never had a relationship with the Clinton campaign." He says they didn't have a contract with the Democratic National Committee until months after the video was purportedly recorded.

Mook says the video is edited and that the full context is unclear. He's calling it an attempt by Trump to "distract from the real issues of this campaign."

Former Arizona governor says Trump being 'waterboarded' by accusers

Former Arizona Gov. Jan Brewer says Donald Trump is being "waterboarded" by his female accusers.

Brewer is a Trump supporter. She's lamenting the "oppression of Donald Trump from all of these women" accusing him of inappropriate sexual conduct.

Brewer says Trump is authentic and "tells it like it is." She's defending his decision to impugn the women during a policy speech on Saturday in Gettysburg, Pennsylvania.

Clinton takes fight to Arizona, long a Republican bastion

PHOENIX (AP) — There's palpable momentum for Democrat Hillary Clinton in Arizona.

The state is so traditionally Republican that her party's nominee for president has carried it just once in the past 64 years.

But long-hungry Democrats are encouraged by Donald Trump's failure to unite the GOP in Arizona. So they're scrambling to capitalize in the campaign's final weeks.

Should they succeed, the loss of Arizona and its 11 electoral votes would further complicate Trump's narrow path to reaching the 270 threshold to win the presidency.
