But McConnell did tell Senate Republicans in their weekly meeting that they needed to prepare for an impeachment trial. The GOP cracks when it comes to impeachment are very limited, but still worth tracking.Republican Rep. Francis Rooney of Florida this past week told CNN, "I don't think you can rule anything out until you know all the facts." Rooney also decided this past week not to seek reelection, which could him more of a wild card in the weeks ahead.Former GOP Gov. John Kasich of Ohio said he would vote yes on impeachment if he were in the House. Kasich was in the House back when President Bill Clinton was impeached. Kasich, though, is a constant Trump critic, so reading too much into his tough criticism would be unwise. But, again, it is worth tracking any Republican dissent or wavering on the impeachment question.
