trump = 'demonstrate'

[Mark Mandel]

      On a corporate level, Harrah's is in the process of picking an
Hispanic agency of record, selecting from two finalist ad agencies,
with a decision expected within the next two to four weeks, Mr. Turman
says.
      The move "really trumps our commitment to Hispanic marketing,"
Mr. Turman says. "We're diving headfirst into it."

Or maybe he means it as = "trumpet" 'announce loudly'.
