PORTSMOUTH, N.H. (AP) — Donald Trump's latest unsubstantiated salvo against rival Hillary Clinton charges she might have been on drugs during their last debate and challenges her to join him in undergoing a pre-debate drug test ahead of their third and final clash.

The claim that the Democratic nominee needed pharmaceutical help took some attention away from whether voters would believe the women who claim that Trump sexually assaulted them or instead accept the Republican's flat denials.

Also overshadowed by Trump's accusation was the release Saturday of yet more emails hacked from accounts of Clinton campaign chairman John Podesta.

Transcripts disclosed by WikiLeaks show the campaign worrying whether Sen. Elizabeth Warren might endorse Bernie Sanders and wrestling with how to respond to revelations about her private email use. Another subject: lining up materials to respond to fresh accusations from Juanita Broaddrick, who accused Bill Clinton of raping her decades ago. He denied the rape accusation, which was never adjudicated by a criminal court.

Other transcripts also show Hillary Clinton generally avoided direct criticism of Wall Street as she examined the causes and responses to the financial meltdown during a series of paid speeches to Goldman Sachs in 2013.

NEW: Koch brothers' network focusing on GOP Senate, not Trump

FAIRLESS HILLS, Pa. (AP) — One of the largest conservative groups in the country isn't promoting the presidential candidacy of Donald Trump as its activists go door to door interacting with voters.

Americans for Prosperity — the best-known group financed by conservative billionaires Charles and David Koch (kohk) — has more than 1,200 employees spread across the country.

Four years ago, that group spent heavily in an effort to prevent President Barack Obama's second term.

This time they're spending about $250 million on policy and politics in the two years leading to Election Day. But they're focusing on saving the Republican-led Senate.

The brothers and many of their wealthy donor friends who fund the political and policy groups known as "the Koch network" have no interest in backing Trump.
