Laura Miller - the city's third female mayor, following Adlene Harrison and Annette Strauss - was instrumental in renegotiating the Wright Amendment to revise flight restrictions at Love Field Airport, as well as implementing a citywide smoking ban and an ordinance prohibiting sex-based discrimination. The following mayor Tom Leppert would impose a staunch crime-fighting policy, promote the economic development of a modern inland port, and was a vocal supporter of a controversial convention center hotel project at the peak of the 2008 recession. He would later vacate the office to pursue a US Senate campaign in 2012, of which he would place third in the runoff. Following the four-month incumbency of acting mayor Dwaine Caraway, mayor Mike Rawlings would be known for his vocal leadership during the 2014 Ebola outbreak, the 2016 shooting of Dallas police officers, and the removal of confederate monuments following the Charlottesville riots.
