Conservatives are making a fresh push to spread their message of fiscal discipline after new estimates that the Medicare and Social Security trust funds will soon be depleted, and amid talk of a $2 trillion infrastructure spending package and busting discretionary spending limits.

The House Republican Study Committee released a budget proposal Wednesday that assumes cutting $12.6 trillion in spending over a decade and eliminating the deficit within six years.

Other GOP lawmakers and conservative groups delivered a similar message on Tuesday, with an emphasis on overhauling entitlement programs such as Social Security and Medicare. House Ways and Means ranking member Kevin Brady and a panel of conservative groups said they were looking at longer-term budget problems.
