Rep. Chris Collins, R-N.Y. pleaded not guilty Wednesday afternoon to federal insider trading charges, according to NBC News. The congressman was arrested earlier in the day on charges that he shared non-public information with family and friends related to Australian biotech company Innate Immunotherapeutics, on which Collins served as a board member. An indictment released Wednesday alleges that Collins, 68, scrambled to call his son from the White House lawn and share information with him about a failed drug trial, and that his son and others then sold stock based on that tip before the trial results became public. Collins' son, Cameron Collins, 25, as well as the father of his fiancee, Stephen Zarsky, 66, were also charged, according to the court filing. All three pleaded not guilty on Wednesday and will be released on $500,000 bond. Collins now must surrender his diplomatic passport and firearms within 14 days.

The next court hearing is set for Oct. 11, less than a month before Collins will face reelection. Collins' indictment has made his deep-red district more competitive for his Democratic opponent Nate McMurray. McMurray jumped on the indictment Wednesday and began fundraising on the news. The Republican representative from upstate New York, President Donald Trump's earliest backer in Congress, suffered almost immediate political fallout in the wake of the charges. In June 2017, according to the indictment, Collins passed nonpublic information about Innate's drug trial results to his son in order to help him "make timely trades in Innate stock and tip others." His son then traded on that inside information and passed it to Zarsky, along with numerous unnamed co-conspirators, "so that they could utilize the information for the same purpose," according to the indictment. Zarsky, too, allegedly traded on the inside knowledge and passed it along to yet more unnamed co-conspirators. In total, the three defendants avoided "over $768,000 in losses that they would have otherwise incurred" had they sold their stock after the information was made public, according to the indictment.

In a statement to CNBC, attorneys for Collins vowed to "mount a vigorous defense to clear his good name." They added: "It is notable that even the government does not allege that Congressman Collins traded a single share of Innate Therapeutics stock. We are confident he will be completely vindicated and exonerated." Later on Wednesday, Collins issued a statement sharing the "very bad news" with his supporters while vowing to continue his re-election fight for the 2018 midterms in November, according to a New York Times reporter. Goldmacher tweet Cameron Collins' attorney, Rebecca Ricigliano, said, "We look forward to addressing these charges in court, and will not be commenting on this case outside of the courtroom." An attorney for Zarsky told CNBC they had no comment at this time. Collins was Trump's first supporter in Congress, and was reportedly a member of his transition team after the 2016 presidential election. The 27th congressional district in New York, which Collins currently represents, voted for Trump at a higher level than any other district in the state in 2016. The indictment related to Innate draws new attention to an ex-Trump administration official: former U.S. Health and Human Services Secretary Tom Price, who was grilled by lawmakers during his confirmation hearings in January 2017 about a tip on the company he allegedly received from Collins. Price resigned last September following an embarrassing series of news stories detailing his use of pricey commercial and charter jet travel during his brief tenure as HHS chief. HHS' Office of Inspector General last month said the department should try to recoup at least $341,000 that Price had wasted on the flights. Just one out of the 21 such flights he took met all federal requirements, the watchdog said in a report. A spokesman for Price told CNBC, "Dr. Price addressed his ownership of Innate Immunotherapeutics stock during his confirmation hearings for HHS Secretary and sold any stock he held in February 2017." The spokesman declined to respond to CNBC's questions about whether Price has been contacted by the DOJ in relation to this case, or if he has hired attorneys. Separately, a source close to Price told CNBC that the former HHS secretary was not questioned by investigators from the Southern District of New York.

Collins had already been probed by the Office of Congressional Ethics, which found in October 2017 that "there is a substantial reason to believe that Representative Collins shared material nonpublic information in the purchase of Innate stock." The committee recommended further review, and the House Ethics Committee was investigating Collins on the heels of that recommendation. The defendants are accused of multiple counts of securities fraud, as well as one count of wire fraud, one count of conspiracy to commit wire fraud, one count of conspiracy to commit securities fraud and one count each of making false statements. The GOP congressman reportedly surrendered to federal agents in Manhattan on Wednesday morning. He is expected to appear in federal court in lower Manhattan later today. Geoffrey Berman, the U.S. Attorney for the Southern District of New York, said at a press conference on Wednesday that Collins "acted as if the law didn't apply to him." Zarsky, Collins and his son each face a maximum of 20 years in prison for each count of the most serious charges in the indictment. Innate did not immediately respond to CNBC's request for comment.
