Saying that the nation doesn't "have time for this kind of silliness," President Barack Obama produced a detailed Hawaiian birth certificate in an effort to quiet those who questioned whether he was born in the United States.

But Julie Moos of the Poynter.org media training institute notes that Obama greatly exaggerated how much attention the issue got from the media.

Moos quotes from Obama's press conference Wednesday:

"...two weeks ago, when the Republican House had put forward a budget that will have huge consequences potentially to the country, and when I gave a speech about my budget and how I felt that we needed to invest in education and infrastructure and making sure that we had a strong safety net for our seniors even as we were closing the deficit, during that entire week the dominant news story wasn't about these huge, monumental choices that we're going to have to make as a nation. It was about my birth certificate. And that was true on most of the news outlets that were represented here."

That's not quite right, Moos reports. She writes:

But numbers provided by Pew's Project for Excellence in Journalism -- which tracks news coverage in its weekly index -- contradict Obama's claim.

For the week of April 11-17, the economy accounted for 39 percent of news coverage.

That same week, Donald Trump's revival of citizenship questions accounted for "much of the attention directly on the Obama administration, at 4 percent of the newshole," PEJ reports.

Last week, Trump did receive more media attention, according to PEJ's index. The 2012 election accounted for 8 percent of the newshole, making it the third biggest story, with 3 percent of the newshole specifically focused on Obama, primarily the question of where he was born.

Some of that coverage was related to Arizona Gov. Jan Brewer's veto of a bill that would have required presidential candidates to provide proof of birth.
