When President Joe Biden announced his intent to rejoin the Paris Climate Accord, Sen. Ted Cruz (R-Texas) was one of the first Republican lawmakers to publicly slam the newly-elected president's decision. Echoing a line from former President Donald Trump, Cruz claimed to be protecting the interests of Pittsburgh over Paris. Almost immediately after he shared his statement via Twitter, critics began firing back.

Now, according to CBS-Pittsburgh, local official Rich Fitzgerald has a message for the embattled Texas senator. When asked about Cruz's remarks, Fitzgerald did not mince words when he expressed his level of disdain for the Republican lawmaker. He also offered a clear message to Cruz: stay out of Pittsburgh business.

"Outrageous. He doesn't know what he's talking about. He's been a climate denier. He was a COVID denier. We believe in science around here," Fitzgerald told KDKA. "We'll run what we need to do here, Senator, and keep your nose out of our business."

Fitzgerald's remarks come just one day after Cruz released a full statement about Biden rejoining the Paris Climate Accord. On Wednesday, Jan. 20, Cruz tweeted, "By rejoining the Paris Climate Agreement, President Biden indicates he's more interested in the views of the citizens of Paris than in the jobs of the citizens of Pittsburgh. This agreement will do little to affect the climate and will harm the livelihoods of Americans."

On Thursday, Cruz tweeted another message that suggested he was standing by his previous remarks.

However, Fitzgerald argued that Biden made the right decision by rejoining the accord as he explained the benefits of addressing environmental issues.

Fitzgerald added, "We have green initiatives that have happened around here, not just with our governmental side of things, but our private sector."

He continued, "It is also improving our quality of life here. So companies continue to grow here."

"Extremists who don't want to do anything, Senator Cruz, who have their head in the sand. The flat-earth society that basically doesn't believe in science," Fitzgerald said, adding, "You have other people who want to shut everything down tomorrow."
