The inquest is due to resume into the death of former Communities Secretary Carl Sargeant.
It is expected to hear evidence from his friends and the General Secretary of the Labour Party, Louise Magee.
At the conclusion of Wednesday's evidence the inquest was told there were text messages between the leader and deputy leader of Flintshire County Council, Aaron Shotton and Bernie Attridge. Mr Attridge said Mr Sargeant would be "shi**ing bricks" in the texts. Mr Attridge was a friend of Carl Sargeant.
Cathryn McGahey QC, representing the First Minister said in the message sent on November 1, Mr Attridge referred to MPs in Westminster being exposed and said AMs would be "on the hitlist".
In a message sent two days after Mr Sargeant was sacked, Mr Attridge said he wished to discourage members of the local Labour Party from supporting Mr Sargeant and implied he had done something which could lead to imprisonment, Ms McGahey said.
Coroner for North Wales (East and Central) John Gittins ruled he would not hear evidence from witnesses relating to the messages.
Bernie Attridge has been asked to comment. The inquest is expected to continue until Friday.
