PHOENIX - Arizona Gov. Jan Brewer will embark on an extensive aerial tour of the Arizona border south of Tucson hours before President Barack Obama is expected to promote his immigration reform plan during Tuesday's State of the Union.
Brewer will meet with reporters in Tucson after the tour to discuss security. The Tucson region is the busiest in the nation for human and drug smuggling.
Obama unveiled his immigration proposal last month. Arizona Republican Sens. John McCain and Jeff Flake are also calling for comprehensive immigration reform.
Brewer has said she won't support immigration reform until the border is secure.
U.S. Customs and Border Protection says the number of people apprehended in Arizona for illegally crossing the border last year dropped to the lowest level in nearly 20 years.
