Another 296 pages of Hillary Clinton’s emails were released Tuesday — exposing key Clinton aides doing favors for billionaires and, on one occasion, leaving the then-secretary of state’s daily schedule in an unlocked hotel room.

The documents were released by Judicial Watch, which is suing to recover Clinton’s emails under Freedom of Information Act laws.

In an April 2009 email to Clinton’s State Department aides Huma Abedin and Cheryl Mills, President Clinton’s former body man, Doug Band, the founder of corporate consultant Teneo, urgently asked them to set up a meeting with an ambassador for a major donor to the Clinton Foundation.

“We need Gilbert Chagoury to speak to the substance person re lebanon. As you know, he’s key guy there and to us and is loved in lebanon.”

“Its jeff feltman,” Abedin wrote back, referring to Ambassador Jeffrey Feltman, America’s former top diplomat to Lebanon. “I’m sure he knows him[.] Ill talk to jeff.”

Less than 20 minutes later, Band replied, “Better if you call him. Now preferrable. This is very important.”

Chagoury is a Lebanese-Nigerian billionaire and a Clinton Foundation donor, giving somewhere between $1 million and $5 million.

The construction magnate has financial interests around the world and was convicted in Switzerland in 2000 for money laundering. He paid $66 million in a plea deal.

The emails also show Clinton’s closest aide, Abedin, left her boss’s daily schedule in an unlocked hotel room in Trinidad and Tobago, where the secretary of state was attending a conference.

“Hi Huma,” aide Melissa Lan wrote in an email to Abedin. “Would it be possible to get one of the Secretary’s day book binders back for tomorrow’s product?”

Abedin replied, “Yes its [sic] on the bed in my room. U can take it. My door is open. I’m in lobby. Thx.”

Judicial Watch president Tom Fitton said in a statement: “No wonder Hillary Clinton and Huma Abedin hid emails from the American people, the courts and Congress. … They show the Clinton Foundation, Clinton donors, and operatives worked with Hillary Clinton in potential violation of the law.”
