Sarah Palin is disputing online reports that she has canceled her bus tour of historic American sites, saying in a Facebook posting that her schedule will be tight the next few weeks because she's been called for jury duty.
Palin said Wednesday that her "One Nation" bus tour would resume "when the time comes." She added that she's looking forward "to hitting the open road again."
The 2008 vice presidential candidate traveled from Washington, D.C. to New England by bus in May in a trip that generated intense interest and fueled speculation about her national ambitions.
Palin is among the top tier of potential 2012 presidential candidates in polls of Republican voters. She has said she plans to visit Iowa, where the state's caucuses begin the nominating season next year.
