One of the state's biggest labs says it's getting out of the COVID testing business, which may cause longer wait times for test results as cases spike.

Stamford-based Sema4 is connected to Gov. Ned Lamont's wife, Annie Lamont. Her venture capital firm owns a small share of the company, which has led to criticism, particularly from likely Republican challenger Bob Stefanowski.

Sema4 says that had nothing to do with its decision to stop offering COVID-19 testing.

In a new government filing, Sema4 says it has "decided to discontinue COVID-19 testing services" – not just in Connecticut, but nationwide.

With more companies now offering testing, "It is the appropriate time to discontinue this line of services and dedicate all the company's efforts and resources on its core mission," Sema4 said.

That mission is genomic testing for patients who want to gauge their risk of disease.

Lamont says Sema4 will leave a big hole - right as demand for tests is spiking.

"Yeah, that's a loss. I mean they were a great testing partner for Connecticut," said Lamont.

But he said he's confident other providers will step up.

"We're talking to our hospital partners. We're talking to everybody else who's providing the testing. They're going to double-down. We're going to provide more testing capacity for this state," said Lamont.

Questions have surrounded Sema4's contracts with the state.

Annie Lamont runs Oak HC/FT, which is an investor in Sema4.

Lamont disclosed the investment to state ethics officials. He also provided a "recusal list" of companies he would not be involved in decisions about.

News 12 asked the governor about Sema4 on News 12 Connecticut's "Power and Politics." John Craven asked if he or his wife had influence in money going to these companies.

"No, zero. None, absolutely. We've got to show beyond a shadow of a doubt, this is an administration with integrity," Lamont said.

Craven asked, "But do you think that maybe indirectly that influenced other people's decisions?" Lamont said no.

"We wanted to be very clear. We put together a list of every single investment we made and made sure our hands were off," Lamont said.

The state Ethics Office says the Lamonts followed the law.

With COVID-19 cases spiking and just one week until Christmas, Craven asked Connecticut's public health commissioner if it is safe to travel and see family and friends this year.

"It can be safe to travel, but you really do need to follow precautions and look at what the restrictions are given to the areas you're going, and where you may be coming back from," said Connecticut Public Health Commissioner Dr. Manisha Juthani.
