Sen. Ted Cruz (R-Texas) was booed off the stage at an event hosted by a Christian organization in Washington, D.C., on Wednesday night.

The conservative firebrand delivered the keynote address at an event hosted by In Defense of Christians (IDC), an organization that raises awareness of persecuted Christian and minority communities in the Middle East. But the audience turned hostile when Cruz said, “Christians have no greater ally than Israel.”

“I will say this: I’m saddened to see that some here, not everyone, are so consumed with hate,” he said, as more members in attendance began to boo. “I will say this: If you will not stand with Israel and the Jews, then I will not stand with you. Thank you, and God bless you,” he said, before walking off the stage.

According to The Daily Caller, IDC Executive Director Andrew Doran then came on the stage and said, “For the love of God, we’re here to talk about Christians and we’re here to be united.”

In a statement issued after the event, the IDC blamed a “few politically motivated opportunists” for the incident.

The Assyrian International News Agency interviewed several attendees, most of whom said they were present “to discuss the plight of the Christians in Iraq, not the Israel-Hamas conflict, and they resented the senator’s attempt to ‘hijack’ the summit,” the agency reports.

In a statement following the incident, Cruz said the event “unfortunately deteriorated into a shameful display of bigotry and hatred.”
