Live from NPR News in Washington, I'm Rylan Barton.

The man accused of spraying a liquid onto Democratic Congresswoman Ilhan Omar during a public event this week in Minneapolis has now been formally charged.

Minneapolis Public Radio's Peter Cox reports.

55-year-old Anthony Kazmirzak is federally charged with assaulting, opposing, impeding, or interfering

with Congresswoman Ilhan Omar's official duties. Tuesday evening at a town hall event in North

Minneapolis, Kazmirzak ran toward Omar as she was speaking, spraying her with a liquid

that the charging document identifies as a mixture of water and apple cider vinegar.

Omar ran toward him with her fist raised before security tackled him.

Then Omar returned to speaking.

Kazmirzak, a Minneapolis resident, was transferred from a county jail into federal custody.

The charging document says his social media includes posts critical of Omar. The Democratic

Congresswoman has been a vocal critic of President Trump and his immigration crackdown. For NPR news,

NPR's Debbie Elliott reports the forecast calls for

dangerously cold temperatures, heavy snow, and strong gusty winds. The National Weather Service

has winter storm advisories posted from the northern plains down the eastern seaboard and all

the way to the Gulf Coast. The prolonged freeze further complicates efforts in parts of the south to recover from an

ice storm that has made travel treacherous and coated trees and power lines. By midday Thursday,

more than 250,000 customers remained without electricity in Tennessee, Mississippi, and Louisiana.

Several states have deployed National Guard troops to help

clear roads and get emergency supplies to communities stranded without power or water.
