The agent also said Clinton acted like she was president while serving as secretary of state from 2009 to 2013 and once made a visibly annoyed President Obama wait for her as she schmoozed with foreign dignitaries at the United Nations.

“She was treating every stop like a campaign stop for the presidency, shaking hands with everyone and looking like a presidential nominee. It was like she was running for presidency for all the years she was secretary of state,” the agent said.

The incident happened in either 2009 or 2010 during the General Assembly as Clinton and Obama were making their way into a Security Council meeting with foreign leaders, the agent said.

“She took her nice sweet time shaking hands and schmoozing with the dignitaries,” said the agent. “She made the president wait to go into the meeting. She was making a fashionably late entrance.”

The agent added, “She was basically saying, ‘I don’t wait for the president, the president waits for me.’ Obama stopped, turned around and rolled his eyes a little bit. He looked at her in a way that inferred, ‘Let’s go.’”

By contrast, the security detail loved former Secretary of State Condoleezza Rice, Clinton’s predecessor who served under George W. Bush.

“Condoleezza Rice was a true diplomat. She built a lot of rapport with her security detail. She would talk to you about family, football, she was one of the boys,” the agent said. “Hillary didn’t care. If you weren’t in her little inner circle — Huma Abedin or Cheryl Mills – she wanted nothing to do with you.”

A Clinton spokesman did not immediately respond to a call or email request for comment.
