NRSC continues attacks over Murphy's resume with new ad

Playing off the concept of an employer verifying an applicant's resume, the National Republican Senatorial Committee has a new attack ad out today on Democratic U.S. Senate candidate Patrick Murphy's embellished resume.

Murphy, a 33-year-old two-term congressman from Jupiter, continues to be widely criticized by Republicans for having inflated his academic and professional credentials -- embellishments that were uncovered by Florida media earlier this summer.

The NRSC has honed in on two of those sticking points for Murphy: his work experience as a Certified Public Accountant and then as a small business owner. Both came under further scrutiny in a CBS Miami investigation in June, which reported that he'd never worked as either.

After that report aired, Murphy's campaign provided more information about his work experiences to Politifact, clarifying the nuances of his credentials. But that hasn't stopped Republican groups from hitting Murphy hard and frequently using CBS Miami's findings.

"Patrick Murphy lied about being a CPA, lied about being a small business owner, and continues to lie about his professional experience even after being exposed as a liar," NRSC spokesman Greg Blair said in a statement. "Murphy is nothing more than an empty suit with a rich father who, with no accomplishments of his own, has resorted to making them up."

The NRSC says its latest 30-second TV spot is "part of a significant NRSC ad buy in Florida." The ad will run in the Tampa and Orlando media markets.

Murphy spokeswoman Galia Slayen said in a statement Wednesday that the NRSC's "claims are flat wrong." She said "Marco Rubio's special interest backers" are trying to distract from the Republican incumbent's own record.

Murphy's campaign has repeatedly brushed off attacks over the congressman's resume. Murphy himself said frequently this summer that the criticisms had been "debunked" by Politifact, even though that wasn't true.

In its initial analysis on Republican attacks of Murphy's resume, Politifact concluded that: "Murphy's description of his past employment is based on actual circumstances, but at times he omits a full explanation." The website did not rate the veracity of the resume attacks on its Truth-O-Meter.
