Florida Sen. Marco Rubio is hitting the campaign trail with Mitt Romney Monday at a campaign event in Astor, Pa., on the eve of the Pennsylvania primary.
Over the weekend, Rubio took the position that he would no longer comment on whether he will be the VP pick or whether he would accept the gig if offered. Immigration activists are planning a press conference nearby to launch a petition protesting Romney's closeness with anti-immigrant politicians such as Kris Kobach and Jan Brewer.
The town hall begins at 12:55 p.m. ET.
