David K. Colapinto is a nationally recognized advocate for whistleblowers specializing in Qui Tam False Claims Act cases and whistleblower reward claims before the SEC, CFTC, and IRS. For more than 30 years he has successfully represented whistleblowers in state and federal courts and before numerous agencies.
Among his many accomplishments, Mr. Colapinto was lead counsel for one of the whistleblowers in a major qui tam/False Claims action against the drug maker Bristol-Myers Squibb, helping to recover more than $500 million for U.S. taxpayers and the government, and he was co-counsel for Bradley Birkenfeld helping to recover the largest ever tax whistleblower award ($104 million) for Mr. Birkenfeld in 2012. He has also successfully handled many other qui tam cases under the False Claims Act and other whistleblower award laws resulting in millions of dollars in recoveries for taxpayers and whistleblowers.
Mr. Colapinto also helped secure whistleblower protections for FBI and Intelligence Community employees. For example, he successfully represented Dr. Fredric Whitehurst, the FBI lab forensics expert who suffered retaliation after reporting serious misconduct and poor lab practices at the FBI. As a result of the Whitehurst v. FBI case, President Clinton ordered the Attorney General to implement the FBI whistleblower statute, but after the Attorney General failed to issue regulations Mr. Colapinto sued the Department of Justice on behalf of other FBI employees to secure their whistleblower rights.
He has also established important precedent under the Freedom of Information Act and Privacy Act. For example, Mr. Colapinto served as co-counsel in Linda Tripp’s successful lawsuit citing Privacy Act violations by the Department of Defense regarding the unauthorized leak of information from Ms. Tripp’s security clearance file following her testimony to the Independent Counsel. In another case, the D.C. Circuit ruled in favor of a different client granting the request for expedited processing under FOIA.
Mr. Colapinto is a co-founder of the National Whistleblower Center where he serves as General Counsel in a pro bono capacity, and a Trustee of the National Whistleblower Legal Defense & Education Fund.

New House Whistleblower Rule Sends A Strong Message
As a new Congress convenes, the House of Representatives will have in place a new rule to protect the identity of whistleblowers who anonymously report wrongdoing to the House. While the new rule was announced by Speaker Nancy Pelosi in response to efforts to unmask the identity of the Intelligence Community whistleblower, whose disclosures led to the impeachment of President Trump over the Ukraine scandal, it will actually strengthen bipartisan Congressional oversight. The new whistleblower rule will follow federal laws providing for whistleblower confidentiality and prohibit House Members from disclosing the identity of whistleblowers who fall under the protection of any federal whistleblower law. The rule would make the disclosure of a federal whistleblower’s identity a violation of the House’s Official Code of Conduct. When House Majority Leader Steny Hoyer proposed the new whistleblower rule in November of 2020, he stated that the purpose of the rule was to promote ...
Qui Tam Whistleblower Action Gets Boost as State Medicaid Program Halts Payments to Clinic Over Medicaid Fraud Allegations
The Medicaid program in Massachusetts has halted Medicaid payments to a Lawrence, Mass. clinic over fraud allegations that were first raised in a leading False Claims Act qui tam whistleblower action that is pending in federal court in Boston, according to a Boston Globe report. The Lawrence counseling clinic is accused of fraud for submitting Medicaid claims for payment of fees for licensed doctors and supervised therapists when in fact patients were treated by unlicensed and unsupervised nurses. The Medicaid fraud allegations were raised by a family whose daughter died while a patient undergoing treatment at the Lawrence clinic. The family filed a qui tam whistleblower action naming as defendants the clinic and its parent company, Universal Health Services, Inc., a publicly traded company that is in the Fortune 500. In June 2016, the U.S. Supreme Court ruled in Universal Health Services v. U.S. ex rel. Escobar that the family ...
Senator Grassley Goes to the Senate Floor to Blast Court Decisions that Place “Bogus Restrictions” on False Claims Act Whistleblower Cases
Senator Chuck Grassley today gave a 15-minute floor speech defending the whistleblower provisions of the False Claims Act and he said that recent court decisions are weakening “the most effective tool to combat government fraud” by “piling on bogus restrictions that are not the law.” Sen. Grassley pointed out that since 1986 the False Claims Act, which was originally enacted under Abraham Lincoln, has enabled the federal government to collect over $56 billion from unscrupulous contractors that have defrauded taxpayers. Last year alone, the government collected $3.7 billion of which $3.4 billion was the direct result of False Claims Act cases filed by whistleblowers. Grassley stated that some False Claims Act defendants are “tying in knots” the lower courts following a Supreme Court ruling last year in Universal Health Services v. U.S. ex rel. Escobar and said defendants and lower courts are misconstruing Justice Thomas’ holding that false claims must be material to the government’s ...
