Republican Sen. Susan Collins of Maine wants the Biden administration to reconsider U.S.-Canada border restrictions that were imposed a year ago because of the pandemic.

Her letter came less than a week after Department of Homeland Security announced that the U.S., Mexico and Canada had jointly agreed to maintain land border restrictions until March 21.

Collins wrote in a letter to DHS Secretary Alejandro Mayorkas that an “equitable solution” is needed for border communities that recognizes lower risk levels.
