Investors worry that the setback Thursday will mean a longer wait for business-friendly policies like tax cuts. Health care and energy stocks fell. Centene fell 4% and Baker Hughes lost 2.3%. Google's parent company, Alphabet, fell 1% after several major companies said they will stop advertising on YouTube because their ads were appearing alongside offensive videos. The Standard & Poor's 500 index fell 2 points, or 0.1%, to 2,345. The Dow Jones industrial average lost 4 points, less than 0.1%, to 20,656. The Nasdaq composite slid 4 points, or 0.1%, to 5,817.
