House Speaker Paul Ryan is refusing to weigh in on Donald Trump's embrace of the "stop and frisk" policing tactic.
The Wisconsin Republican said Thursday that he hasn't given it enough thought to comment.
Trump asserted earlier Thursday that Chicago needs stop and frisk to bring crime under control.
A federal judge has ruled New York City had used the practice unconstitutional because of its overwhelming impact on minority residents.
Ryan said he doesn't know enough about the tactic to comment about its constitutionality or efficacy.
Ryan has deflected questions on other Trump proposals too by saying he doesn't know enough to comment.
