MOUNTAIN HOME, Ark. (AP) — A northern Arkansas man who allegedly made threatening phone calls to CNN anchor Don Lemon has pleaded not guilty.

The Baxter Bulletin reports Benjamin Craig Matthews, 38, appeared in Baxter County Court Thursday . Matthews, who is from Mountain Home, about 110 miles (177 kilometers) north of Little Rock, is free on $15,000 bail.
