President Joe Biden touted his administration’s efforts to clean up the Great Lakes Thursday alongside endangered Ohio Rep. Marcy Kaptur, part of the Democratic Party’s efforts to defy expectations in the midterm elections.

Biden and Environmental Protection Agency Administrator Michael Regan met Kaptur in Lorain, Ohio, marking the president’s second trip to support a Democrat facing tough reelection odds in as many weeks. On Feb. 10, he championed Virginia Rep. Abigail Spanberger’s work on prescription drug pricing, and he praised Kaptur throughout his remarks on Thursday for motivating much of his administration’s efforts to clean up the country’s polluted waterways.
