Sen. Bernie Moreno (R-Ohio), a close Trump ally, announced Thursday that he will introduce legislation to sanction Canada and Canadian officials over the huge wildfires that have poured smoke and haze across the United States, creating hazardous air-quality conditions.

“I’ll be introducing a bill next week to sanction Canada and the responsible Canadian government officials for this atrocity,” Moreno posted on social media.

The Ohio Republican reposted an image of a deserted boulevard in Cleveland with buildings shrouded in haze.
