After the White House released President Obama’s long-form birth certificate this morning, Donald Trump took credit for the move. “I’m very proud of myself because I’ve accomplished something nobody else has been able to accomplish,” Trump said modestly.

But Trump may have accomplished something else, too: He may now find himself pressed to answer whether he’ll release his tax returns.

George Stepanopoulos reminds us that he recently asked Trump in an interview if he’d release his tax returns if Obama released the birth certificate Trump has been demanding. Trump responded:

“Maybe I’m going to do the tax returns when Obama does his birth certificate. I may tie my tax returns. I’d love to give my tax returns. I may tie my tax returns into Obama’s birth certificate.”

I’ve asked a Trump spokesperson whether he will now release his tax returns in light of this morning’s development.

The question of whether Trump will follow through no this suggestion goes directly to the heart of whether Trump’s presidential flirtation has been a big fraud all along. Those who say it’s a ruse argue that Trump will never run for president, because he’d have to reveal that his net worth is far less than he’s claimed. Trump, who bristles at this suggestion, sought to dispel such talk by suggesting to Stephanopoulos that he’d release his tax returns if Obama released his birth certificate — apparently thinking he was secure in the knowledge that Obama would never do this. Now Trump’s bluff has been called.

It will be interesting to see if Trump — whose demand for Obama’s birth certificate has been the subject of two days of questioning during White House press briefings — will now face any serious media pressure to come clean in his own right.
