'[13] Halloran attracted widespread attention when he stated that five municipal employees had told him of a deliberate slowdown in clearing snow after a blizzard in December 2010.

[14] Halloran's study of the Viking Age and field research in Ireland led him to develop an interest in Germanic paganism, and eventually to Theodism,[7] which has attracted widespread attention.

Halloran also stated that "It is our hope to reconstruct the pre-Christian religion of the Germanic branch of the Indo-European peoples, within a cultural framework and community environment."

These sentiments were echoed by the Queens County Republican Party chairman, Phil Ragusa, who additionally described Halloran as "a traditional person" and "a regular guy".

The report pointed out that when Halloran was elected in an off-year campaign, he was the "'First Atheling' or prince, of his own Theodish tribe, called New Normandy.

On April 2, 2013, Halloran was arrested along with Democratic New York State Senator Malcolm A. Smith, Bronx Republican Party Chairman Joseph J. Savino, Queens Republican Party Vice Chairman Vincent Tabone, Spring Valley Mayor Noramie Jasmin, and Spring Valley Deputy Mayor Joseph Desmaret, on federal corruption charges.

As part of the scheme, Halloran allegedly facilitated the Smith bribes and also accepted over $18,000 in cash from an undercover agent and a cooperating witness.

[25] On July 29, 2014, Halloran was convicted of taking bribes, orchestrating payoffs, and participating in the scheme to help Democrat Smith to run for mayor on the 2013 ballot as a Republican.

He was convicted both of acting as a liaison between Smith and Republican Party officials and of taking at least $15,000 in bribes for designating about $80,000 in New York City funds to a nonprofit entity, allowing the money to be embezzled through a no-show job.
