The troubles continue to mount for Rep. Chris Collins. The House Ethics Committee has established an Investigative Subcommittee to review the charges against Collins outlined in a federal indictment. It's a serious development, so say two Washington observers who follow congressional matters. They also note the Justice Department has requested the Subcommittee delay its investigation until the federal charges are resolved. That conclusion may come after Collins, who has suspended his reelection campaign, is out of office.
