BERLIN, GERMANY - JUNE 18: Mourners attend a vigil for victims of a shooting at a gay nightclub in Orlando, Florida nearly a week earlier, in front of the United States embassy on June 18, 2016 in Berlin, Germany. Fifty people were killed and at least as many injured during a Latin music event at the Pulse club in the worst terror attack in the U.S. since 9/11. The American-born gunman had pledged allegiance to ISIS, though officials have yet to find conclusive evidence of his having any direct connection with foreign extremists. The incident has added fuel to the ongoing debate about gun control in the country. (Photo by Adam Berry/Getty Images)

A former US marine allegedly planned to carry out an attack on Pier 39 in San Francisco over the holidays, according to a criminal complaint filed in court in California today. Everitt Aaron Jameson had supported ISIS on social media and discussed his plans with undercover FBI employees to conduct a San Bernardino or New York style attack, using weapons and explosives, in San Francisco. A search warrant was executed at his home on Wednesday and authorities found his will, and a letter saying ìlong live Abu Bakr al-Baghdadi,î saying ìyou all have brought this upon yourselves,î and charging ìyouíve allowed Donald Trump to give Al Quds away to the Jews,î in a reference to Jerusalem. He goes on to say ìWe have penetrated and infiltrated your disgusting country.î The FBI documents reveal that firearms, empty magazines, ammunition, and fireworks were also found at his Modesto home. The complaint also says Jameson was discharged from the Marine Corps for ìfraudulent enlistmentî for failing to disclose ìa latent asthma history.î
