(CNN) - House Democratic leaders on Monday refuted embattled Rep. Eric Massa's allegation that they want to get rid of him because of his opposition to health care legislation.
"That's completely false. There is zero merit to that accusation," said Katie Grant, spokeswoman for House Majority Leader Steny Hoyer, D-Maryland.
An aide to House Speaker Nancy Pelosi, D-California, also denied Massa's claim.
Massa, D-New York, announced Wednesday he would not seek re-election because of health concerns and denied reports that he had harassed one of his Capitol Hill staff members. Two days later, he said he would resign effective Monday.
The first-term congressman said he learned of an ethics investigation into his conduct after deciding to retire.
