The U.S. House of Representatives Committee on Ethics has decided to extend its review of Republican Congressman Chris Collins’ stock market activity. According to a press release Monday, the matter was transmitted to the committee from the Congressional Ethics Office on July 14.

“The Committee notes that the mere fact of a referral or an extension, and the mandatory disclosure of such an extension and the name of the subject matter, does not itself indicate that any violation has occurred, or reflect any judgment on behalf of the committee,” the Chairwoman and Ranking Member wrote in a joint statement.

Democrats, including Congresswoman Louise Slaughter, have raised questions about whether Collins helped his friends and colleagues buy shares of Australian pharmaceutical company Innate Immunotherapeutics at a discount, while using his influence to make the company more valuable. In May, investigators reportedly interviewed some of his associates in Western New York.

“The House Ethics Committee is reviewing a report from the Office of Congressional Ethics in regards to the false accusations brought about by Congresswoman Louise Slaughter and her allies in a partisan witch hunt against Congressman Collins,” spokesperson Sarah Minkel said. “Today’s announcement was expected and is nothing more than a pro forma delay because Congress is currently in its August recess. Congressman Collins has followed all ethical and legal guidelines when it comes to his personal investments and he looks forward to their review.”

The Democratic Congressional Campaign Committee, however, argued the committee’s decision Monday was significant. The DCCC is targeting the congressman’s seat in 2018.

“It’s hard to overstate how damaging this is for Representative Collins,” spokesman Evan Lukaske said. “Not only is the investigation into his potentially unethical stock trading continuing, but we now know that there is ‘substantial reason to believe’ Collins violated either the law, House rules, or both. This isn’t what Western New Yorkers voted for last year—I’m sure that for many, Election Day can’t come soon enough.”

The Ethics Committee said it would announce its next course of action before October 12.
