Conservative columnist Michelle Malkin on Thursday accused President Barack Obama of “child abuse” because she said he had used children as “kiddie human shields” to advance his gun safety agenda.

On Wednesday, a number of children — who had written the president calling for action after the December Sandy Hook Elementary School shooting — joined him at the White House as he signed 23 executive orders and proposed that Congress take action to curb gun violence, including universal background checks, banning assault weapons, banning high-capacity magazines and outlawing ownership of armor-piercing bullets.

Fox News host Steve Doocy on Thursday told Malkin that “some on the right” — like himself — had accused Obama of using the children as “props.”
