Michelle O'Neill has denied Sinn Féin believes it is not subject to the law.
The deputy first minister faced more criticism in the Assembly today over her attendance at the funeral of former leading republican Bobby Storey.
Police are investigating whether any breaches of Stormont's coronavirus social distancing regulations occurred after hundreds lined the route of the cortege in west Belfast last week.
TUV leader Jim Allister said: "She and her friends think that they have the right to break the very law that they themselves make."
He told the Assembly: "Equality is to subject yourselves equally under the law."
Sinn Féin vice-president Ms O'Neill said she had dedicated her job to promoting equality.
"I breathe equality," she said.
She repeated her previous comments made about her attendance at the funeral.
A motion urging her and Finance Minister Conor Murphy to apologise is being debated at the Assembly this evening.
