Social Protection minister Joan Burton has said she has full confidence in Alan Shatter.
Joan Burton said she was happy the Dáil record had been corrected, and that a policing authority would be set up.
"I'm very pleased that he made the apology, that corrected the record of the house and, yes, I do have confidence in him," she said.
The Minister failed to answer questions on whether the details of Martin Callinan's letter to the Minister were shared at Tuesday's Cabinet meeting.
She also said she did not know how many times Martin Callinan was spoken to by civil servants in the run-up to his resignation.
"I'm just aware of what the Taoiseach talked about in the Dáil…I'm not aware whether or not there were other discussions other than what was talked about in the Dáil," she said.
