The senators' request comes just days after a trio of mass shootings in California that killed 19 people. Earlier in the month, a 6-year-old boy with a handgun shot and seriously wounded a teacher in Virginia.

"The law says you shouldn't be marketing guns to kids. But there's a company in Chicago that's doing just that," Schumer said of Wee 1 Tactical.

Republicans have largely opposed such measures, saying they infringe on the right to keep and bear arms enshrined in the Second Amendment of the U.S. Constitution.
