Government websites in the United States, mainly from Ohio, were hacked on Sunday around 11:00 a.m. to display a pro-Islamic State message.
"You will be held accountable Trump, you and all your people for every drop of blood flowing in Muslim countries," a message from "Team System Dz" said. "I love Islamic State."
The websites of Republican Ohio Gov. John Kasich, Ohio First Lady Karen Kasich, the Ohio Department of Rehabilitation and Correction, the Casino Control Commission, and the state's Medicaid program were all hacked, the Associated Press reported.
Republican Ohio Treasurer and Senate candidate Josh Mandel tweeted a picture of the message left by the hackers.
OH Dept of Corrections website right now, this is what you see. Wake up freedom-loving Americans. Radical Islam infiltrating the heartland. pic.twitter.com/dRll4aNiwQ

The same message was left on government websites in Brookhaven, N.Y. and Howard County, Md.
Tom Hoyt, chief communications officer for Ohio's Department of Administrative Services, confirmed the websites had been hacked.
"All affected servers have been taken offline and we are investigating how these hackers were able to deface these websites," Hoyt said. "We also are working with law enforcement to better understand what happened."
"Team System Dz," which previously expressed support for ISIS, has claimed responsibility for past hacks in Richland County, Wis. and outside the country in Scotland and Sweden.
