Washington (CNN) -- Rep. Anthony Weiner has said he has no plans to resign over a "sexting" scandal, and that his wife wants him to stay in Congress, a Democratic source told CNN Thursday. Weiner made the remarks to a House Democratic colleague from New York on Wednesday afternoon, rejecting growing calls from fellow legislators -- including key Democrats -- for him to step down, said the source, who was familiar with the conversation. Weiner also cited polling data showing a majority of New York City voters want him to remain in office, the source said, describing Weiner as "dug in."
