With the threat of $4-a-gallon gas once again hanging over the economy -- and over President Obama's re-election campaign -- the White House on Friday left the door open to tapping the country's oil reserve to ease prices. 

"A release of the Strategic Petroleum Reserve is an option that's on the table," Deputy Press Secretary Josh Earnest told reporters. 

The response was boilerplate, and Earnest added that he didn't "have anything to announce further on that topic at this point." 

But Earnest also wasn't disputing a news report Friday claiming the White House was "dusting off old plans" for potentially releasing some of that oil. That claim, attributed to an anonymous source, was made in a lengthy Reuters piece that suggested a decision might come after Labor Day -- when officials can better gauge the trend in prices. 

Lately, that trend has been ever-upward, and it's being felt at the pump. The average price of a gallon of regular Friday was $3.72, up 29 cents from last month.
