“Look, it is not appropriate for any candidate for federal office, certainly, including a sitting president, to ask for assistance from a foreign country. That’s not appropriate, but I don’t know that’s what happened there,” Toomey said.

Toomey also said that he didn’t know what was the substance of Trump’s conversation with the Ukrainian president.

“I mean, at this point, we don’t know anything. We’re getting a bunch of leaked rumors and that’s all we have,” he said. “There might be a reasonable explanation for this, and there might be a troublesome one, and we should understand why that happened.”
