House Majority Whip Steve Scalise, R-La., said Sunday most of the Freedom Caucus was behind the House Republican's tax plan ahead of an expected vote on the Tax Cuts and Jobs Act this week.
"We've been working really well with them," Scalise told "Fox and Friends."
"I talk to Mark Meadows on a regular basis, and most of the members of the Freedom Caucus that we've talked to, they are really supportive of this bill, as are most members of our conference."
Meadows, R-N.C., chair of the conservative group, has already stated his opposition to Senate GOP members' proposal to phase in cuts to the corporate tax rate.
"Obviously there are going to be some folks that we are going to talk to this week that aren't yet there, but are going to get there," Scalise continued.
Earlier on Sunday, Rep. Peter King told Fox News' "Sunday Morning Futures" program he still needed to be sold on the bill.
Scalise said Sunday he intended to whip votes Monday.
