House lawmakers next week will make their first attempt at advancing a 2018 budget proposal that would serve as the vehicle for comprehensive tax reform.

Majority Leader Kevin McCarthy, R-Calif., announced Friday the House Budget Committee plans to mark up the fiscal 2018 spending blueprint next week. A Republican aide confirmed the plan and said an official announcement about the planned markup will come on Monday.

Consideration of the budget comes after weeks of internal wrangling between GOP lawmakers.

Conservatives have balked at the spending cuts offered so far. They want more than the $200 billion in mandatory spending reductions offered by GOP leaders, but more moderate members of the conference oppose anything more significant.

The budget is supposed to dictate the top line numbers for the appropriations bills. But House lawmakers have already moved ahead with those measures and are expected to approve all 12 appropriations bills in committee by next week.

Earlier this week, Republicans appeared divided on the budget plan.

"We're still having the listening sessions with our members on the budget," House Speaker Paul Ryan, R-Wis., said on Wednesday.
