President Joe Biden said Saturday that he regrets using the term “illegal” during his State of the Union address to describe the suspected killer of Laken Riley, as his all-but-certain 2024 rival Donald Trump blamed Biden for her death at a rally attended by the Georgia nursing student’s family. Biden expressed remorse in an interview Saturday after facing frustration from some in his party for the use of the term to describe people who arrived or are living in the U.S. illegally. The term was once common but is far less so today, particularly among Democrats who more fully embraced immigrant rights’ issues during Trump’s presidency.
