The ad says Rubio "opposes immigration reform. Worse, Rubio supports Donald Trump. His plan would deport 800,000 children, destroying families."

Murphy is pushing Rubio's position too far when he says Rubio opposes immigration reform. After a comprehensive bill with a path to citizenship failed in 2013, Rubio called for a piecemeal approach with border security first. He still wants to change immigration laws, but he believes it is politically impractical to do it in one swoop.

Some immigration advocates argue that Rubio’s piecemeal approach is a delay tactic and kicks a path to citizenship even further down the road.

Rubio does support Trump, who has said he will overturn a program that temporarily allows Dreamers to avoid deportation, affecting about 740,000 people. That action by itself would leave those undocumented immigrants to face the threat of deportation. Rubio has said he supports a legislative replacement for DACA.
