Civil rights groups are calling for the collapsed Baltimore bridge to be renamed when it's rebuilt, citing accusations of racism against national anthem author Francis Scott Key. Leaders argued that the The Star-Spangled Banner author -who the collapsed bridge was named after - was a slave owner who wrote lyrics that scholars have said 'demeaned black people.' They have asked for the bridge to be renamed after late congressman Parren J Mitchel, the first black man from Maryland elected to the US House of Representatives.
