The alleged neo-Nazi man accused of ramming a rented U-Haul truck into White House security barriers will be held in federal jail pending a detention hearing next week, according to reports.

Sai Varsith Kandula, 19, appeared in a Washington D.C. federal court Wednesday, where Magistrate Judge Robin M. Meriweather ordered he be jailed until a hearing next Tuesday, CBS News reported.

Kandula, from Missouri, careened the box truck into barriers along Lafayette Square just steps from the White House late Monday night, US Park Police officials said.

He had allegedly planned the attack for six months with his goal being to “get to the White House, seize power, and be put in charge of the nation,” records show.

Kandula allegedly said he would “Kill the President If that’s what I have to do,” and praised Nazism and Hitler.

The 19-year-old was originally charged with threatening to kill, kidnap or inflict harm on a president, vice president or family member, as well as assault with a dangerous weapon, reckless operation of a motor vehicle, trespassing and destruction of federal property, US Park Police said.

Upon leaving the U-Haul truck, Kandula was seen waving a Nazi flag.

His federal charges have since been downgraded to a single count of depredation of property of the United States in excess of $1,000.
