Washington (CNN) The Trump administration is preparing a package of legislative measures responding to a spate of recent mass shootings, aides said Monday, even as White House and congressional staffs remain far apart on the best path forward.

The package will include legislation that would expedite the death penalty for people found guilty of mass killings, Vice President Mike Pence's chief of staff told reporters.

The issue assumed new attention following another shooting over the weekend in West Texas, which killed seven people and wounded almost two dozen others.
