As Democrats struggle to counter President Donald Trump on trade policy, Sen. Bernie Sanders pledges to renegotiate the U.S.-Mexico-Canada agreement if he's elected president, citing the lack of provisions to address climate change.

The Senate overwhelmingly passed the Trump administration’s revision of the North American trade pact with Canada and Mexico, sending the deal to the White House where the president has said he may sign it in a grand ceremony next week.

Agricultural policy has seldom received as much attention as it has in this presidential campaign as Democrats vie for ways to cut into President Donald Trump’s rural base and win Iowa’s first-in-the-nation’s caucuses amid heightened anxiety about the farm economy.

Democratic presidential hopefuls are raising alarms and lashing out at President Donald Trump’s handling of the dispute that’s expected to escalate even further next month.
