It is unclear whether she plans to fight the charges.

Bowie, from Albany in upstate New York, had allegedly discussed her plans with FBI informants and spent weeks with agents posing as IS members.

She selected the New York statehouse in Albany because she thought it would be an easier target than the White House, prosecutors say.

“I want it to have an affect on the American system,” she allegedly told agents. Prosecutors say she visited the building at least five times on reconnaissance missions ahead of the attack.

As part of her plot, she planned to use a food delivery bag to hide her bomb, officials say. The charging documents include an image of the DoorDash bag she brought to agents.

Agents allegedly also gave Bowie $200 (£147) to buy bomb making material from a local hardware store. They drove her to the Home Depot store, and when she emerged from the store she allegedly said she hoped those were the right kind of nails.

“I hope the nails are big enough… because the nails work as shrapnel, right?” she allegedly told the two undercover operatives.

She was arrested on Wednesday, and was also found carrying knifes, and a written oath of allegiance to IS, according to the complaint.
