President Barack Obama told his top donors Wednesday night that releasing the long-form version of his birth certificate illustrated the serious nature of his job. As Obama wooed donors in New York City in an attempt to keep that job, the president joked the day had been “fun,” adding a quip: “Nobody checked my ID at the door.

“But it was also a serious day because part of what happened this morning was me trying to remind the press and trying to remind both parties that what we do in politics is not a reality show,” Obama said at the fundraiser, held at former New Jersey Gov. Jon Corzine’s Fifth Avenue apartment.

Earlier Wednesday, the White House released for the first time the long version of the document proving Obama was born in Hawaii, deflating conspiracy theories that have chased the president since his first campaign. He’d compared the fervor over his citizenship to distractions created by “sideshows and carnival barkers.”

Obama spoke to 60 people during the dinner at Corzine’s apartment, to a group of about 350 people at the Waldorf Astoria and at a “Gen44” town hall event for 1,300 younger supporters.

The three fundraisers support a joint account of the Democratic National Committee and Obama’s re-election campaign, known as the Obama Victory Fund. An official estimated the three events could raise $2 million to $3 million.

The president told his supporters it would not be an easy re-election campaign but praised his own record. He said that even though he was not “satisfied with the progress we’ve made,” he feels the nation is “on the right track.”
