Rep. Marsha Blackburn, R-Tenn., slammed the Obama administration Tuesday for its enforcement of the Deferred Action for Childhood Arrivals policy, blaming it for the influx of child migrants at the Southern border.

Blackburn said the policy was “unlawfully created” when issued by the Department of Homeland Security in 2012 and said the executive action was another example of President Barack Obama “circumventing” Congress. The Tennessee Republican is pushing legislation to defund DACA along with Sen. Ted Cruz, R-Texas.

“Sadly, the president and the Democrats have moved from the party of ‘yes we can’ to the party of ‘because we can,’” Blackburn said.
