(CNN) – Mitt Romney's campaign appointed two staffers for its eventual vice presidential pick Tuesday as speculation increases on the timing of the closely watched decision.
Randy Bumps, an executive at the public affairs firm Direct Impact, joined Team Romney as director of operations for Romney's vice presidential candidate, and Kevin Sheridan, who CNN reported last week was joining Romney's campaign as a senior adviser, was named as communications director for the running mate.
"I'm proud to add Randy and Kevin to our growing team," Romney Campaign Manager Matt Rhoades wrote in a statement. "They both have enjoyed long and distinguished careers in our party. Their work will be vital as we move forward in the campaign to defeat President Obama and elect Mitt Romney."
Before joining Romney's campaign last week, Sheridan served as a senior vice president at the Edelman public relations firm.
He was press director for the U.S. Agency for International Development under the administration of President George W. Bush, and through 2004 was a spokesman and director of regional media for the Republican National Committee.
On Monday, a top aide to Romney denied that the presumptive GOP nominee had settled on a pick for his vice presidential running mate.
Eric Fehrnstrom, speaking to reporters in Baton Rouge, Louisiana, following a fund-raiser, said "No decision's been made on V.P."
His remarks came after a report in the New York Times cited friends of Romney saying the candidate had made his choice for running mate and was preparing to announce his pick as early as this week.
Speaking to CNN National Political Correspondent Jim Acosta, Fehrnstrom would not speculate on the timing of the announcement.
"It could happen anytime between now and the convention but it will only happen after a decision has been made and no decision has been made," Fehrnstrom said.
