WASHINGTON — Facing an end-of-the-month deadline, the Obama administration is calling gun owner groups, victims' organizations and representatives from the video-game industry to the White House this week for discussions on potential policy proposals for curbing gun violence.

President Barack Obama has ordered an administration-wide task force to send him proposals by the end of January. The group, led by Vice President Joe Biden, was formed in response to last month's horrific massacre of 20 children and six adults at a Newtown, Conn., elementary school.

Biden will meet Wednesday with gun violence victims' groups and gun safety organizations, a White House official said. On Thursday, he will hold talks with gun ownership groups, as well as advocates for sportsmen. The vice president also plans to meet this week with representatives from the entertainment and video-game industries. The official was not authorized to discuss the meetings before they were publicly announced and thus spoke on condition of anonymity.
