Federal prosecutors on Thursday said they plan to file felony charges against the man who was arrested last week with firearms in former President Barack Obama's Washington, DC, neighborhood and accused of threatening several politicians.

Taylor Taranto, who had an open warrant for his arrest related to charges stemming from his involvement in the US Capitol riot, was arrested last week after claiming on an internet livestream the day before that he had a detonator.

Taranto has been in police custody since his arrest, and during a hearing Thursday to determine whether he'll continue to be detained pending his trial for the riot charges, federal prosecutors said they plan to add federal felony charges to the case.

The prosecutors did not say when exactly they would bring the additional charges. Taranto is currently only facing four misdemeanor charges related to his conduct on January 6, 2021.

Taranto will continue to remain in custody pending a decision on his detention, federal magistrate Judge Zia Faruqui ordered Thursday.

Faruqui said he is currently in contact with Washington state pretrial services to see if Taranto could be supervised for by a third-party custodian instead of detention. Pretrial services informed the judge it could take up to a week to evaluate the case.

Taranto is set to have another detention hearing next Wednesday.
