...The creation of the group comes as Mr. Sanders faces lingering disappointment from some of his supporters for his endorsement of Mrs. Clinton and questions about his finances that have arisen since he left the race.
During the primary race, Mr. Sanders repeatedly delayed releasing his financial disclosure information, and ultimately never did. This month, he spent nearly $600,000 on a vacation home in Vermont near Lake Champlain.
Republicans in Mr. Sanderss home state have taken notice of his post-campaign behavior and his new political organization and accused him of violating his own principles.
He preaches transparency and then he tries to set up the most shadowy of shadowy fund-raising organization to support his causes, said Brady Toensing, the vice chairman of the Vermont Republican Party, who argued that Mr. Sanders was essentially a big donor. What Im seeing here is a senator who is against big money in politics, but only when its not his big money, he said.
Paul S. Ryan, a campaign finance expert at the Campaign Legal Center, a nonprofit political finance group, said that it was unusual for a federal lawmaker to set up such a fund-raising organization and that Mr. Sanders should have to follow the donation limits and disclosure requirements to be in compliance with the Federal Election Commission.
There are definitely some red flags with respect to the formation of this group that are worth noting and keeping an eye on, Mr. Ryan said. Were in a murky area.
