WASHINGTON (Reuters) - U.S. House Speaker Nancy Pelosi, the top Democrat in Washington, on Friday said President Donald Trump was "sowing chaos over the border" with his threat to slap tariffs on Mexican imports, and she called on him to work with Congress on immigration reform.

"We hope that the president will join us in bipartisan comprehensive immigration reform, be strategic about our trade relationships and recognize the importance of the U.S.-Mexico relationship," Pelosi said in a statement.

"Yet again, the president is sowing chaos over the border instead of delivering solutions for American workers and for American consumers," she added.
