A leading GOP senator emphasized the need for Republicans to maintain their congressional majority to fix Obamacare, which he said is collapsing due to high prices.

Sen. Lamar Alexander, R-Tenn., said in the weekly GOP address that his home state recently announced major price hikes of up to 62 percent for 2017 Obamacare plans. He then pivoted to the need to maintain control of Congress no matter what happens with the presidential race in November.
