Paris climate talks: Democratic senators say they 'will not back down'

Group of 10 lawmakers pledge to defend president's environmental agenda in Congress, citing 'promise from the American people to the world'

Democratic senators staged a show of force at the Paris climate meeting on Saturday, pledging they "had Barack Obama's back" and would defend his agenda in a Republican-controlled Congress.

The appearance by 10 Democratic senators, days after Congress voted to repeal new power plant rules, was intended to demonstrate solid political support for Obama's climate plan - despite Republican claims to the contrary.
