LAS VEGAS (AP) — Hillary Clinton's presidential campaign is opening its first official campaign headquarters in Las Vegas.

The Democratic frontrunner has been building up a staff in Nevada for months, but the office will offer a centralized hub for phone banks, canvassing and other activities. An office launch event is scheduled for Thursday evening.

Clinton has visited Nevada twice since May. She's one of an array of presidential candidates, mostly Republicans, who are making campaign stops in Nevada to rally support in the early-voting state.
