"Sen. Susan Collins (R-Maine) is joining a group of Democrats who are seeking to overturn a Trump administration rollback of the regulation of methane, a greenhouse gas that’s significantly more potent than carbon dioxide.
She’s now a co-sponsor for legislation that would nix the Trump methane rule by using the Congressional Review Act (CRA), a spokesperson for the senator confirmed.
The CRA allows Congress to get rid of regulations completed in the prior 60 legislative days, to nix the Trump methane rule."
