Washington (CNN) – Will it spark an altercation between tea party activists and establishment Republicans?
On Monday, leaders and supporters of FreedomWorks - a major tea party sponsor - will make an unscheduled visit to the offices of the National Republican Senatorial Committee, the group that helps elect Republicans to the Senate. And the activists will deliver a message to the NRSC: butt out of the Utah senate race.
At issue: Republican Sen. Orrin Hatch's re-election to a seventh term in 2012.
As FreedomWorks works to deny Hatch an eighth term, the group is infuriated that the NRSC will work to keep Hatch in office. Adam Brandon, a national spokesman for FreedomWorks, laid out to CNN what activists intend to do during their Monday visit.
"At about 12:30 p.m. [EST] today, our Utah [members,] probably about 15 of them, will be joined by about 30 others of the tea party activists and they're going to storm the [National] Republican Senatorial Committee and ask them to stay out of Utah," Brandon said. He added: "Because they've thrown in with Hatch."
FreedomWorks' Washington office is just blocks away from those of the NRSC. And the NRSC has said that Sen. John Cornyn does support Hatch's re-election.
When asked if he expects any altercation during the visit, Brandon said, "I wouldn't call it an altercation. But usually when you do something like this, they don't want to talk. And our guys will get a little steamed that someone won't come down and talk with us. Then eventually someone will."
"One thing that this movement does is, we travel where the battle is. We run to the sound of the gun," Brandon added. "This is probably Orrin Hatch's worst nightmare. This race is probably going to get nationalized."
The group feels Hatch - who has a history of working with Democrats - is not a strong enough conservative and recently launched a "Retire Orrin Hatch" campaign.
Russ Walker, FreedomWorks' vice president of political and grassroots campaigns, recently told CNN: "Indeed Hatch's body of work proves he cannot be trusted to consistently adhere to a fiscally conservative agenda and possible primary challengers like Representative Jason Chaffetz, R-Utah, give conservatives in Utah and around the country a great opportunity to trade up."
Aware of the coming visit, NRSC Communications Director Brian Walsh would not criticize it or the activists.
"We respect their views just as we respect the views of others who are strongly supporting Senator Hatch's re-election, including [conservative radio talk show host] Mark Levin and C. Boyden Gray who is the co-chairman of the FreedomWorks Foundation Board," Walsh said in a statement. "But as Vice-Chairman of the NRSC, few people have worked harder than Orrin Hatch to help Republicans win back the Senate next year and Senator Cornyn is proud to support him."
Yet Hatch's campaign manager was far more blunt.
"Well that's interesting, they say butt out of the Utah race. Yet a week ago they came to the Utah Republican convention with a bunch of out-of-staters to try and tell Utahans what to do," Dave Hansen told CNN. "The Utahans were telling them: we know what we [want.] We can handle this ourselves in state."
"This is organized by a bunch of Washington, D.C. special interest groups to try and get some media," Hansen added.
Stressing that Hatch has been a "conservative his entire time in the U.S. senate, Hansen said: "Sen. Hatch has represented the state very well. And he's campaigning very hard. And in the end he's going to win."
