Dear US Senator Robert Menendez,
In light of your request that Alex Salmond, First Minister of Scotland, Jack Straw, MP, former Justice Secretary, and Scottish Justice Secretary MacAskill, attend a US Senate hearing, I request and demand that you go boil your own head with immediate effect*.
The UK and Scotland are not answerable to your office, position, president, judiciary or nation. Should you wish to speak to our politicians on matters concerning the UK or Scotland, it is normally performed via Diplomatic Channels or, failing that, a request to visit the UK and speak directly with the offices concerned.
Your behaviour exhibits gross arrogance, unwarranted entitlement, extraterritorality and Authoritarianism. You are in the Democrat Party, so one should not be at all surprised.
* Should you not possess a pot of sufficient girth in which to boil your head, leave a comment and we can see if something might be fabricated should Harland and Wolff be willing and have a spare month or so.
