Cruz took perhaps the boldest swipes at the president and his request for $3.7 billion in emergency funding to address the issue. Cruz was also the only one of the group to speak on the floor this week.

Paul remained mostly quiet, having published an op-ed during the Independence Day holiday that criticized the country’s immigration policy broadly but did not directly address the minors streaming across the border. He’s also withholding comment on the president’s funding request until there is written legislation, according to spokesman Sergio Gor.

Rubio, who finds himself in perhaps the most awkward position because he supported the Senate’s immigration bill last year, defended his position while jabbing at Obama.
