Republican Sen. Tom Cotton said GOP members of the House should not “walk the plank” by approving the Republican health care bill, warning that it could cost the party the House majority and put the entire GOP agenda at risk. “I would say to my friends in the House of Representatives with whom I serve, ‘Do not walk the plank and vote for a bill that cannot pass the Senate and then have to face the consequences of that vote,” Cotton told ABC News chief anchor George Stephanopoulos.
