WASHINGTON (AP) — They're the oddest of Senate odd couples.
Yet California Democrat Barbara Boxer and Oklahoma Republican Jim Inhofe have accomplished something highly unusual in a bitter election year: significant, bipartisan legislation on the environment that has become law.
Boxer is a staunch liberal who calls climate change the "greatest challenge to hit the planet."
Inhofe is an unabashed conservative who dismisses global warming as a hoax.
Still, they've managed to become friends and political partners.
Earlier this year, Inhofe and Boxer shepherded a sweeping law imposing new regulations on tens of thousands of toxic chemicals.
They've played key roles on a $305 billion law to address the nation's aging and congested transportation systems. And they've secured overwhelming support for a bill to address a lead-contaminated water crisis in Flint, Michigan.
