During an interaction with reporters, Singh allegedly used abusive words when journalists asked him about the Bill submitted by the NC.
Initially, the minister told the reporters that they should ask questions only about his department.
"I have nothing to do with that. If you have to ask questions, ask about health. If health is there, then everything is there. Don't get into rubbish things," the minister said.
This is not the first time that Singh has found himself mired in a controversy.
