(The Center Square) -As the government shutdown enters its second day, House Speaker Mike Johnson, R-La., defended Republican leaders’ refusal to concede to Democrats’ health care policy demands in exchange for their votes on federal funding. "Don't ask the Republicans what we should be doing or what we should be negotiating. I don’t have anything to negotiate,” Johnson told reporters Thursday. By refusing to negotiate now on health care policy and refusing to pass Democrats’ $1.4 trillion counterproposal, Republicans “own” the shutdown, Democrats argue. In a change of plans, however, Thune canceled a Saturday vote, meaning the shutdown would last through the weekend.
