The House erred in focusing on Trump’s intent to promote himself at someone else’s expense. What he actually did was much more eggregious—he offered an American citizen up to the judicial inquisition of a foreign country. When the U.S. did that under a prior administration to foreign national, it was called “extraordinary rendition.” Although Biden was not actually handed over to the tender mercies of Ukraine’s corrupt judicial processes, the offer was unambiguous. No wonder Bolton bailed.
On the other hand, kidnapping migrants at the border is an on-going illegal enterprise, as is the practice of people having to be ransomed with monetary payments. Declaring normal human behavior (in this case perambulation) to be a crime is not new (eating, drinking, association, reproduction, sleeping have all been targeted) but it is still despicable.
