The mayor of Imperial Beach, which abuts Tijuana, Mexico at a point that is visible by a border wall marking the two countries, is fed up with sewage and toxic chemicals flowing into the United States, and he is heading to Washington, D.C., to ask the Trump administration to do something about it.

Imperial Beach Mayor Serge Dedina left for the nation’s capital on Sunday with a congressional delegation. He told Border Report that he has meetings at the White House scheduled on Tuesday with top officials who he hopes will help this situation.
