*Republicans in crosshairs of 6 January panel begin campaign of intimidation.* They are trying to intimidate phone companies that the House investigation has given subpoenas for the phone records of officials that worked for the coup leader.

According to one model, the climate impact of a transatlantic flight could cost global economy $3,000 over the course of this century.
