Sen. Ted Cruz, R-Texas, stepped off a plane and into a crowd of protesters Sunday at Los Angeles International Airport who chanted "free the children" as he waited for his luggage.
The chant was a reference to detention centers at the southern border.
Cruz can be seen in video posted to Twitter smiling, shaking a few hands and even taking pictures with some fellow travelers as the group chanted.
The Texas conservative has been a staunch supporter of President Donald Trump's border security policies.
