"Let's vote on the Green New Deal!" Graham, a Republican, tweeted Friday. "Americans deserve to see what kind of solutions far-left Democrats are offering to deal with climate change."

Graham knows the Green New Deal would never pass Congress. In fact, Democrats aren't united behind the bill, which moderates fear will alienate key bases of their support, including unions.

Democratic New York Rep. Alexandria Ocasio-Cortez unveiled the Green New Deal bill Thursday, and Massachusetts Sen. Ed Markey introduced a companion bill in the Senate.

The resolution calls for "10-year national mobilizations" to fighting global warming by eliminating all carbon dioxide emissions from all sectors of the economy, including the power industry, agriculture, transportation and every building.
