BUFFALO, N.Y. — The woman arrested at the Peace Bridge who is accused of sending a letter with ricin to President Trump faced a federal judge Tuesday.

Pascale Ferrier is charged with threatening the President of the United States.

The judge adjourned for the day because Ferrier requested an identity hearing and a preliminary hearing — meaning they need to prove that she is the suspect they’re looking for and probable cause. 

Ferrier was arrested Saturday when she tried to enter the U.S. from Canada.

According to the federal affidavit, she had a loaded gun in her waistband and a knife.

She allegedly made statements to U.S. Customs and Border Protection officers referencing "being wanted by the FBI for the ricin letters."

The letter was post marked from Canada.

According to the affidavit, the letter said in part, “I made a special gift for you to make a decision. This gift is in this letter. If it doesn't work, I’ll find better recipe for another poison, or I might use my gun when I’ll be able to come. Enjoy."

Authorities say six additional letters were given to FBI offices in Texas that appeared to be similar.

They say those letters also contained a powdery substance.

Ferrier was arrested by Mission, Texas police in March 2019 for weapons possession and was transferred into Immigration and Customs Enforcement custody.

Canadian authorities are working with the FBI and the Secret Service on the case.

Ferrier's attorney Fonda Kubiak says she feels Tuesday's court appearance went as planned.

Ferrier is due back in court later this month.
