The host of NBC's "Late Night" Jimmy Fallon took to Twitter to ask his followers what he should ask tonight's guest, Sen. John McCain (R-Ariz.)

The former Saturday Night Live star specifically requested that audience members submit questions on healthcare reform. The new media-savvy Fallon has previously used Twitter to collect questions for celebrities appearing on his show.
