SALT LAKE CITY — Chia-Chi Teng, who's challenging Rep. Jason Chaffetz, R-Utah, at the state GOP convention Saturday, is running radio commercials criticizing the congressman for supporting a $1.1 trillion federal spending bill in 2014.

The commercial, airing on KSL Newsradio, features an anonymous announcer tripping up over how much money was involved in the bill and questioning why Chaffetz would vote for that as a conservative.

"Don't know," a producer answers. GOP senators "Ted Cruz and Mike Lee didn't vote for it, neither did Marco Rubio, but Chaffetz did, joining the D.C. establishment, adding to the national debt, hurting the economy and killing jobs."

Teng then asks voters for their support "because it's time for Washington to start living within its means."

The January 2014 budget bill came several months after the federal government shutdown that resulted from a fight against President Barack Obama's signature health care law.

Chaffetz said he voted for the bill, as did the other three House members of Utah's all-Republican congressional delegation.

"You're going to have a hard time convincing anybody I'm not conservative enough," said Chaffetz, who was first elected in 2008.

State Republican delegates will vote for their pick for the District 3 seat in Congress on Saturday. Teng gathered enough voter signatures to qualify for a place on the primary ballot, but Chaffetz needs to win the support of 40 percent of the delegates.
