Cincinnati (US): A man accused of plotting to attack the US Capitol called a television station from jail and said if he hadn't been arrested, he would have gone to Washington and put a gun to President Barack Obama's head.

WXIX-TV in Cincinnati said Christopher Lee Cornell, 20, called the station from the Kentucky jail where he's being held, confessed to being a supporter of the Islamic State group and said he planned to kill government officials in retaliation for US strikes on the militant organization.
