WINSTON-SALEM, N.C. (CBSNewYork/AP) — Hillary Clinton’s campaign is once again on the defensive after a new wave of leaked emails obtained by WikiLeaks pulls back the curtain on the Clinton Foundation.

CBS2’s Dick Brennan reports a hacked memo reveals how former White House aide Doug Band worked to obtain “in-kind services for the President and his family – for personal travel, hospitality, vacation and the like.”

Emails also show how Band’s company Teneo helped secure business for former President Bill Clinton from donors who were giving to the Clinton Foundation, including two paid speeches to Barclays totaling more than $700,000. Laureate International Universities paid him $3.5 million to serve as honorary chairman.

The former president has since severed his ties with Teneo, which says in a statement that it “worked to encourage clients, where appropriate, to support the Clinton Foundation because of the good work that it does around the world.

These hacked WikiLeaks emails also show that Clinton campaign aides have long been concerned about how this web of donors and clients would look to the public.

This comes as Hillary Clinton and first lady Michelle Obama campaigned together for the first time at a rally in Winston-Salem, North Carolina.

“When you hear folks talking about a global conspiracy and that this election is rigged, understand that they are trying to get you to stay home, they are trying to convince you your vote doesn’t matter,” Mrs. Obama said at the rally.

Trump is in Ohio as polls are tightening. A new national poll has Clinton leading by six points in a four-way race, down from nine just a few days ago.

Trump went after Clinton about the latest batch of emails.

“Mr. Band called the arrangement unorthodox, the rest of us call it outright corrupt,” Trump said.

“Some in the media are calling it Bill Clinton Incorporate,” Republican vice presidential nominee Mike Pence said.

The question, however, is can the continuing drip of WikiLeaks cost Clinton even more votes.

“I think for a lot of voters, this feels like inside baseball for them,” said John Heileman of Bloomberg Politics.

Millions of votes that have been cast already in the U.S. presidential election point to an advantage for Hillary Clinton in critical battleground states. Data compiled by The Associated Press also show signs of Democratic strength in traditionally Republican territory.

The strong early-voting turnout by those likely to support Clinton could leave Donald Trump with virtually no path to the 270 electoral votes needed for victory.

Clinton is showing strength in Florida and North Carolina, both must-win states for Trump, as well as the battleground states of Nevada, Colorado and Arizona. There are even favorable signs for Clinton in Republican-leaning Utah and Texas.

Early voting is underway in 37 states. More than 12.5 million votes have been cast, far higher than the rate in 2012.
