Rep Trey Gowdy & Constitutional Rights

CNN/s Jake Tapper asked House of Representatives Member Republican Trey Gowdy what the problem was with increasing the waiting period to get a gun so that a more thorough background check could be completed.  Rep Gowdy replied that extending the waiting period delayed fulfilling a citizen's Constitutional Rights.  Why didn't Jake ask a follow up - then why is it acceptable to delay a woman's right to an abortion by either having a 72 hour waiting period or shoving an ultrasound up her vagina?
