Your attorney would urge you not to speak out on the allegations; to the point of ending his/her representation if you insisted.
An example to the negative is Martin Shkreli, the individual who drastically raised the cost of drugs after acquiring the companies. He was on trial for fraud to his investors. Both before and during his trial, his attorneys told him not to publicly speak out on not only the trial, but any issue. Shkreli continued to speak out re trial on public media and press conferences. Eventually, during the trial, the prosecutors and his lawyers made a motion to gag Shkreli, which was granted.
Now, his statements were of no importance for the case at trial; however, during the sentencing the prosecutors can bring up every one of his statements to show a lack of remorse and a lack of respect for the trial and/ or defrauded investors, in order to seek a higher sentence and fines.
True, his attorneys were not going to threaten their representation; hourly 4 figure billing would make one hesitant to walk away. But I am sure he was warned strenuously about the affect on sentencing. It is likely he ignored it because he was positive he would not be convicted.
