A White House spokesman declined to comment Thursday on a congressional proposal to require women to register for the draft.

Although the House Armed Services Committee voted Wednesday to change that policy, presidential press secretary Josh Earnest said he could not comment because of a pending class-action lawsuit on the issue.

Earnest said the committee's move would "attract a lot of attention," and that the litigation limits what he can say.

However, President Obama welcomed Defense Secretary Ash Carter's proposal to open all combat roles to women, Earnest said.

Earnest also said that although he hasn't asked the president about it, he has not heard him support a bill that would reinstitute the draft sponsored by Rep. Charlie Rangel, D-N.Y. Obama is quite proud of America's all-volunteer force, Earnest said.
