A federal judge ruled on Tuesday that Congressman Doug Lamborn will get his name on the Republican primary ballot.

But some say that ruling did not necessarily place him back into the election.

Shortly after 11 News talked to Rep. Lamborn Tuesday afternoon, the group whose lawsuit got him off the ballot, told us the fight isn't over yet.

Last week, the Colorado Supreme Court ruled that Rep. Lamborn fell short of the required number of signatures to appear on the primary ballot.

A federal judge heard arguments in an appeal on Monday and announced the ruling Tuesday afternoon.

The six-term GOP hardliner, representing Colorado’s 5th Congressional District, needed 1,000 signatures to be included in the June 26 primary.

In an effort to get Lamborn removed from the ballot, some Republican voters, Republican lawmakers and one of his opponents sued the Secretary of State claiming that Lamborn used paid petition circulators that weren’t Colorado residents.

"When you endorse somebody, when he's having trouble in his election and he turns around and tries to destroy you politically, that's kind of backstabbing in my opinion,” Lamborn said Tuesday.

The congressman from Colorado Springs hired the firm Kennedy Enterprises to collect the 1,000 signatures required to put him on the ballot for the 2018 5th Congressional District primary.

"I did everything properly and maybe some of the people who were hired by the people I hired didn't follow through. Although even they tell me and I double checked, they checked all of the voter registrations,” Lamborn said.

Secretary of State Wayne Williams had approved Lamborn’s ballot petition on March 29.

Earlier this month, a lower court ruled those signatures could stay but the plaintiffs appealed the decision and the Supreme Court ruled against Lamborn.

Lamborn says the Supreme Court ruling violates First Amendment rights because requiring signature gatherers to live in Colorado violates the U.S. Constitution.

Tuesday a federal judge ruled the secretary of state can put Doug Lamborn on the ballot if the signature collectors' residency is the only thing that's keeping him off.

An opposing group tells 11 News they're considering legal options.

State Sen. Owen Hill and Darryl Glenn, who challenged Democrat Michael Bennet for his U.S. Senate seat in 2016, also are in the GOP race.
