Yes he did!

Fueling suspicions of anti-Israel leanings, Prez-elect Barack Hussein Obama reportedly had his people meet with Hamas' people in the Gaza Strip during the campaign. At least that's what Hamas claims. 

Ismail Haniyeh's political advisor said the Islamist group met with Obama aides after an email exchange, but was told to keep the meeting a secret. Well, no longer a secret. Ahmed Yousef, Haniyeh's political advisor, said: "We were in contact with a number of Obama's aides through the Internet, and later met with some of them in Gaza, but they advised us not to come out with any statements, as they may have a negative effect on his election campaign and be used by Republican candidate John McCain (to attack Obama)."

Contact with Obama's advisors is ongoing, Yousef said.  The Obama camp has not yet commented on this report.

Because Hamas is on the US State Department terrorist list, America hasn't negotiated with the organization yet. Yet.
