The sudden cancellation of the impeachment vote and the warning issued to Donald Trump signal deep divisions within Congress and a strategic recalibration by Democrats. It underscores the political volatility surrounding Trump's actions and the difficulty of holding him accountable in a hyper-partisan climate.

A long-shot effort by Democratic Rep. Shri Thanedar to force an impeachment vote against President Donald Trump was abruptly pulled Wednesday evening after a group of Democrats signaled they would vote with Republicans to block the move.

Rep. Shri Thanedar of Michigan announced his intention to charge ahead, saying that as an immigrant to America he wants to do all he can to protect its Constitution and institutions from Trump's lawlessness. His resolution contains seven articles of impeachment against the Republican president.
