Thin on the right so far
None of the 12 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
Federal authorities are investigating a series of letters containing suspicious substances that have been mailed to election and government officials across the United States. The U.S. Postal Inspection Service is leading the inquiry into the incidents. Reports indicate the letters contained an unidentified white powder. The Minnesota Secretary of State's office confirmed receiving such a package, which was intercepted before reaching its destination. These events appear connected to similar mailings sent to officials nationwide.
Disagreement on specific targets
While multiple reports confirm letters were sent to election and government officials, specific targets vary. MPR News states the letters were sent to congressional and election offices nationwide. The Star Tribune reports the incidents appear connected to mailings sent to U.S. senators and election offices nationwide. The Louisiana Illuminator notes letters were mailed to elections offices and capitol buildings in multiple states, including Louisiana. Grand Rapids Herald-Review and Minnesota Reformer state a package with a threatening letter and white powder was intercepted before reaching the Minnesota Secretary of State's office. Winona Daily News reports a similar package was intercepted before reaching the Minnesota Secretary of State's office, and CBS News states a threatening letter with white powder was addressed to the Office of the Minnesota Secretary of State. KSTP News reports suspicious letters were sent to the Minnesota Secretary of State's office and Senator Amy Klobuchar's office.
What the coverage left out
