Washington Examiner Executive Editor Bob Cusack said the Iran war is posing a major challenge for Republicans as negotiations paint a troubled picture for the midterm elections.“A deal has got to happen very soon for Republicans because this war is not popular,” Cusack said Friday on C-Span’s Washington Journal.Voters have heard of promised deals “dozens of times” from President Donald Trump, Cusack said.

Trump claimed Friday morning that ceasefire deals reported by Iranian officials were “fake news.”

Cusack defended parts of the negotiations, saying it is hard to verify information because a lot of the Iranian leaders are in hiding, which in turn has led U.S. officials and the public to question whether they can be trusted.

This sense of uncertainty is beginning to shape Republican support for Trump, alongside already minimal to zero support from Democrats.

“Portions of the Right who supported this deal are already very skeptical of this deal, or any reported deal over the last several weeks,” Cusack said.
