WASHINGTON (AP) — Maine Republican Sen. Susan Collins says she’ll vote for her party’s tax bill this week.

The moderate’s support means all voting GOP senators are expected to back the measure. That’s enough to approve the $1.5 trillion package.

Collins cited provisions she says she helped win, including letting people deduct state and local income, sales and property taxes up to $10,000.

The House-passed version limited that to property tax deductions up to $10,000. Current law generally allows all local taxes to be deducted without limit.

Collins was among a handful of Republicans who helped derail her party’s effort this year to scuttle the “Obamacare” health law.
