Topeka ? Republican Sens. Pat Roberts and Jerry Moran of Kansas say any proposal to raise the federal debt ceiling must have tax-reform provisions they say will stimulate the economy.

Roberts and Moran both said Wednesday they’re studying rival proposals being considered in Congress.

One is a House package to cut spending and force a balanced budget. Moran says the GOP-sponsored plan shows a willingness to raise the debt ceiling, and should not be rejected immediately by the Senate.

Roberts said he was reviewing a plan brokered by six senators that would raise the debt ceiling and cut federal spending. He adds that any package must include tax reform to stand a chance of passing.
