HENDERSON, Nev. (AP) - Michelle Obama is coming to southern Nevada to campaign for her husband less than two weeks after the president visited Las Vegas.

The first lady is set to visit campaign volunteers in the Henderson area on Tuesday afternoon. The trip is part of a larger western states tour that will have Obama delivering an Oregon State University graduation speech on Sunday and meeting with Colorado campaign volunteers on Wednesday.

Michelle Obama visited Sin City at the beginning of May. Her speech touted her husband as someone who understands middle-class struggles.

She also brought her daughters to Las Vegas as part of a family vacation in March.

President Barack Obama has made four trips to the Silver State this year.

Nevada is an important swing state in November's presidential election.
