WASHINGTON (AP) -- Legislation to renew long-term jobless benefits appears headed toward Senate gridlock as Democrats object to Republican demands that the cost be offset so deficits don’t rise.

Republicans outlined several alternatives to cover the estimated $6.4 billion price tag of the three-month bill.

One called for delaying a requirement for individuals to purchase health insurance under "Obamacare." A second is aimed at preventing immigrants living in the country illegally from claiming a certain type of tax break for their children. A third would stop individuals who receive Social Security disability payments from also claiming unemployment benefits.

Democrats say they oppose paying for the legislation. The former program expired on Dec. 28 and 1.3 million long-term unemployed suddenly lost benefits averaging $256 a week.
