After months of vomiting up falsehoods about election fraud to please Donald Trump, it might have been a good idea for Sen. Ted Cruz (R-TX) to just quieten down for a little while. But, true to form, he’s bumbled into the Biden era with some fresh nonsense. In a clueless attack on President Joe Biden’s decision to re-enter the Paris Climate Agreement—the flagship international treaty to tackle the climate crisis—Cruz failed to wrap his head around why Biden backs a deal signed in France. Paraphrasing an old Trump line, he wrote: “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.” His misunderstanding, whether it was wilful or not, has been treated with the derision it deserves. Rep. Alexandria Ocasio-Cortez wrote: “Nice tweet Sen. Cruz! Quick question: do you also believe the Geneva Convention was about the views of the citizens of Geneva?”
