Prosecutors say the U.S. Secret Service and local authorities collaborated to arrest Brent Dickinson of Saratoga Springs.
The county district attorney's office said Saturday the 33-year-old man "intended to murder" the targets of his threatening messages. They said the U.S. Secret Service intercepted two threatening messages posted by Dickinson on a White House message board Friday.
Dickinson was arraigned in Saratoga Springs City Court on charges of making terroristic threats.
He was taken to city jail after bail was set at $50,000. It wasn't immediately known Saturday whether he had an attorney.
A message left at a number listed for Dickinson's possible relatives was not returned Saturday.
