Senate Minority Leader Chuck Schumer slammed Republicans for their efforts to repeal and replace Obamacare after the Congressional Budget Office said Monday it would lead to roughly 24 million more people being uninsured over a decade.

The CBO “score” – a much-anticipated analysis of the GOP measure’s impact on the deficit and number of uninsured Americans – should serve as a “looming stop sign” for the Republican efforts, Schumer said.
