Donald Trump has a lot of supporters, but there's no dearth of those who fancy seeing him lose the Nov. election as well, with some disliking him to the extent of trying to take his life. One such attempt was prevented when US authorities arrested a woman suspected of sending a letter laden with the poison ricin to the president.

The woman was trying to enter the United States from Canada at a border crossing located in New York state, a US law enforcement official revealed. The woman was carrying a gun and was arrested by US authorities, according to the law enforcement official.

US prosecutors in Washington, DC are likely to bring charges against the woman. Two law enforcement officials had prevented a ricin package addressed to Trump from reaching him last week, and investigators were looking at the possibility that the package came from Canada, CNN previously reported.

A person involved in the investigation told CNN's Josh Campbell the letter containing a granular substance bearing an outward appearance of ground castor beans was mailed from St. Hubert, Quebec. The letter was tested twice to confirm the presence of ricin, the insider said, adding that all mail addressed to the White House is screened and sorted at an offsite facility before it reaches the White House.

A Royal Canadian Mounted Police spokesperson confirmed Saturday that it was working along with the FBI to check the matter thoroughly, telling CNN that the RCMP isn't ready to release a statement, confirm or deny any reports on arrests. An FBI Washington Field Office spokesperson confirmed that an arrest was made and the investigation is ongoing.

FBI's Washington field office released a statement to CNN on Saturday, noting that the FBI and its U.S. Secret Service and U.S. Postal Inspection Service partners are reviewing a suspicious letter sent to a U.S. government mail facility. There was no known threat to public safety at the time, the statement added.

Authorities are also checking other similar packages sent to addresses in Texas that could be from the same Canadian sender, a US law enforcement official said. a chief spokeswoman for Canada's Minister of Public Safety Bill Blair, Mary-Liz Power said they are aware of the alarming reports of packages with ricin sent to US federal government sites.

Power said the Canadian law enforcement is working alongside their US counterparts, noting that they are unable to comment further since this is an active investigation. A highly toxic compound, Ricin is extracted from castor beans and can be sued in acid, mist, pellet, or even powder form.
