The House of Representatives will pause late Monday for a moment of silence to honor the 20 children and six adults killed in the mass shooting in Newtown, Conn., Republican House Majority Leader Eric Cantor announced. The Senate held its moment of silence after returning to work at 2 p.m.
Cantor made the announcement on Twitter.
"Tonight, the House will observe a moment of silence in honor of the victims of the Sandy Hook Elementary School shooting and their families," he wrote.
The solemn tribute comes as lawmakers gird for what could be a new battle over gun control in the aftermath of the tragedy. Several Democrats have pushed for restrictions including curbs on the sale of large ammunition clips and for renewing the assault weapons ban that lapsed in 2004.
President Barack Obama has signaled support for some kind of official response without giving any details, and it's unclear whether any gun control measures can pass the U.S. Congress.
