Here I'll do it for you:
A transrectal ultrasound (TRUS) is an ultrasound technique that is used to view a man's prostate and surrounding tissues. The ultrasound transducer (probe) sends sound waves through the wall of the rectum into the prostate gland, which is located directly in front of the rectum.
So essentially the ad suggests that we anally probe Ted Cruz.
Which if you think about it makes perfect sense, because I am pretty sure that is where his ideas originate.
