During an eight-day stretch this month, one of the four Democrats running for mayor, Rep. Anthony Weiner, mailed roughly 86,000 newsletters to constituents through his congressional office.

According to Mr. Weiner’s campaign spokesman, Anson Kaye, the taxpayer financed mailings came in five versions and had a combined cost of $115,213.

They were postmarked just before the June 15 start of a blackout period, in which candidates are barred from sending mass mailings through their government offices for the 90 days leading up to an election in which they appear on the ballot.

The Democratic mayoral primary election is set for September 13.

Mr. Weiner’s mailings, of which Mr. Kaye sent electronic copies to The New York Sun, touted the congressman’s efforts to fight for homeland security funds for New York City, to secure money for Jewish groups, to keep Catholic schools open, and to lower gas prices, among other things.

One of Mr. Weiner’s mailings featured two photos of him talking to men and boys wearing yarmulkes. The text touted Mr. Weiner’s support of Israel and his work to return to Hungarian Holocaust survivors many heirlooms that were confiscated by Nazis and pro-Nazi governments.

They were sent at the same time questions were being raised about a series of mass mailings that one of his mayoral rivals, Gifford Miller, the speaker of the City Council, sent out through the council.

Those mailings were sent to homes in many parts of the city, not just in Mr. Miller’s district. Like Mr. Weiner’s House mailings, they featured several pictures of the office-holder and repeated mentions of his name.

While Mr. Weiner’s House mailings touted achievements of the congressman, much of Mr. Miller’s text was devoted to criticism of Mayor Bloomberg’s policies.

Mr. Miller’s council spokesman, Stephen Sigmund, said the cost to the city was $37,000 for printing and postage.

Last week, a third Democratic mayoral candidate, C.Virginia Fields, asked both the city’s Campaign Finance Board and Conflicts of Interest Board to investigate whether Mr. Miller’s mailings violated any regulations.

Staff members for both Messrs. Miller and Weiner said the mailings are a standard way to communicate with constituents.

Mr. Kaye said Mr. Weiner’s mailings were sent “exclusively within the congressional district” and were approved by the House Ethics Committee.

Regulations for House mailings seem to be more stringent than those governing the City Council. The House franking rules specify exactly how many times a member can make personal references, for example, and specifically bar autobiographical information.

“We are in complete compliance with every applicable ethical rule,” Mr. Kaye said. The mailings, he said, “followed the letter of the law.”

The congressman, whose district straddles Brooklyn and Queens, sent out nine mailings last year – when he won a fourth term in November – at a total cost of $194,000, compared to seven so far this year at a cost of $158,000, Mr. Kaye said.

“There were fewer mailings this year than there were the year before,” Mr. Kaye said. “It’s a shorter time period this year than in previous years.”

Mr. Weiner’s material also explicitly says that it was paid for with taxpayer money, while Mr. Miller’s does not.

Separately, both Mr. Weiner and Mr. Miller are among the candidates who have sent out campaign literature – paid for by their campaign committees in recent weeks.
