POLITICO's Reid Epstein reports:

On a Romney campaign surrogates conference call to bash President Barack Obama's stewardship of the economy Wednesday morning, officials faced a series of questions about the campaign's recent argument that 92 percent of jobs lost during the recession were held by women.

Three separate times the surrogates, who included Lanhee Chen, the campaign's chief policy adviser, were asked what specifically about Obama's policies are bad for women, and three times the campaign offered no specifics.

And then Sam Stein of the Huffington Post asked about the first bill Obama signed as president, a bill lifting the statute of limitations for women who sue to receive equal pay for performing the same jobs as men.

"Does Gov. Romney support the Lilly Ledbetter Act?" asked Sam Stein of the Huffington Post.

After a six-second pause, an unidentified voice replied, "Sam, we'll get back to you on that."

The Romney press aide arranging the call did not immediately respond to requests to clarify Romney's position on the act.
