Taoiseach Leo Varadkar was accused of "talking of peace while beating the war drums" and "wasting taxpayers' dime" in complaints over the recent visit of US president Joe Biden.
The 46th president of the United States visited Ireland from April 11th-14th. He was the eighth sitting American president to visit Ireland and the trip included an historic address to the Dáil and a large public speech in Ballina, Co Mayo.
While the trip was seen as a success, others were not so happy with the welcome for Mr Biden.
In a number of letters and emails to the Taoiseach, seen by BreakingNews.ie after a Freedom of Information request, Mr Varadkar was told Mr Biden's Dáil address was "no JFK moment" and that the visit was "political grandstanding".
In an email received on the first day of the trip, a "part Irish" American wrote: "I thought you should know that the Biden administration plans on bringing over 300 guns to your country."
This was not elaborated on, but it may have been a reference to the Secret Service agents protecting the Democratic president.
The email went on to tell Mr Varadkar he should be aware of something which was redacted due to 'Security, Defence and International Relations' by the Department of the Taoiseach.
The "American citizen" added, "take precautions he's very", before another redacted portion.
Other complaints referred to the cost of the State dinner for Mr Biden at Dublin Castle.
One email, addressed to Mr Varadkar and Tánaiste Micheál Martin, was complimentary of the visit as whole, with the person writing Mr Biden "comes across as a lovely humble man, with a great sense of humour".
However, they were critical of the presentation at Dublin Castle. "It looked so plain. I never saw a room so plain for visits from presidential and dignitaries to dine in. When the Queen was here many years ago, it looked much better and much more glamorous.
"The wooden floors and the plain chairs left a lot to be desired. The royal blue wall background however, was lovely."
Unlike the other messages, it finished on a positive note: "Otherwise, well done on the great organisation regarding Mr Joe Biden's wonderful visit. I know he thoroughly enjoyed it too."
An email on April 14th with the subject line 'biden @the dail and Dublin castle' was much more critical in tone.
The person referred to the "spectacle in the castle where the great and the good came out to feast on the taxpayers dime".
Mr Biden's Dáil address was very well received but the author of this email claimed listeners were "bored to the eyeballs".
'No JFK moment'
It went on: "This was no JFK moment in history when he addressed the dail [sic] with clarity, graciousness and integrity, the people loved him, not this [redacted]".
John F Kennedy was the first US president to address Dáil Éireann, in 1963. Mr Biden became the fourth president to speak at Leinster House after Kennedy, Ronald Reagan and Bill Clinton.
The email concluded: "Keep up the good work in yere [sic] minoritising us Irish."
Another email, also on April 14th, opened: "Well Taoiseach, while you're [redacted] with all this [redacted] wining, dining and luxuriating on all the trappings and high office using the public purse, you would do well to remember what you are supposed to be doing: serving the Irish people!"
It accused Mr Varadkar of forgetting "the homeless and hungry" while "you're savouring the food served at the banquet laid out in Dublin Castle".
The person wrote: "Your speech at the banquet at Dublin Castle was exactly what I expected from you; espousing the very values you and your government undermine: faith, family, freedom and the idea of a nation-state and country."
They also accused Mr Varadkar of "self-congratulatory political grandstanding" and "talking of peace while beating the war drums".
A letter to the Taoiseach from a business owner complained about road closures into Dublin city, and the fact that "some of our customers were told to work from home all this week".
The business owner asked for compensation and asked whether their complaint should be addressed to the Government or Dublin City Council.
