The spending bill the House GOP is preparing will include language targeting the health law's contraception mandate.
The language would ban the enforcement of the contraception mandate, allowing businesses to not offer birth control coverage to their employees.
The amendment is expected to be added to the funding-measure, which will pass the House but looks to be dead in the Senate.
The language on birth control says the section of ObamaCare dealing with contraception coverage would not be effective until 2015, a delay of longer than a year if the measure were passed in the coming days or weeks.
The bill says the requirement would not apply before 2015 "with respect to the requirement for specific coverage for any sponsor of a group health plan (or, in the case of student health plans, the institution of higher education offering such plans), health insurance issuer, or individual opposing such requirement for coverage based on religious or moral objections."
More broadly, the amendment would delay all ObamaCare provisions for one year, starting from the date on which they were due to take effect, for any provision with a due date through 2014.
The amendment also delays all implementation related to the IRS, and blocks fees associated with non-compliance with the law.
