Assemblywoman Claudia Tenney announced on Tuesday she would launch a second campaign for a House of Representatives seat held by fellow Republican Rep. Richard Hanna.

“Politicians in Washington tell us what we want to hear in the district, but vote the opposite when they go to Washington,” Tenney said in a statement released by her campaign. Hanna continues to surrender our principles on the steps of the Capitol and sides with the President and Democrats to keep his seat in power.”

The primary will likely be one of the more closely watched Congressional races in New York, if not the country given Hanna’s moderate credentials and reputation.

Tenney’s announcement comes weeks after Hanna inflamed Republicans when he suggested in a radio interview the House GOP-led investigation into the Benghazi attacks were a politically driven effort to discredit Hillary Clinton, the leading Democratic presidential candidate.

“I think that there was a big part of this investigation that was designed to go after people – an individual: Hillary Clinton,” Hanna told a radio station in October.

Hanna’s comments came after House Majority Leader Kevin McCarthy in an interview made a similar suggestion, a comment that ultimately sunk his effort to succeed House Speaker John Boehner.

“We need a representative in Congress who has the courage to challenge the power brokers in Washington and the tenacity to fight for our Republican values,” Tenney said. “Richard Hanna continued his assault on our principles when recently he ridiculed Republican Representative Trey Gowdy’s investigation into the Benghazi murders as little more than a partisan attack against Hillary Clinton.”

Tenney plans to make her announcement in three different locations around the 22nd congressional district: Binghamton, Sherburne and Utica.

Tenney last ran against Hanna for the Republican nomination in 2014, starting relatively late that year and faced a barrage of independent expenditure ads released on Hanna’s behalf.

Hanna won, 53 percent to 47 percent.

Hanna did not face a Democratic opponent that fall.
