Seán Canney has told RTÉ News he still has not decided about his future in the Independent Alliance.
It is the Galway East TD's first public comment after it emerged earlier this week that he was considering his options as a member of the grouping.
It comes after the Alliance decided last week that Kevin Boxer Moran should remain as Minister of State for the Office of Public Works for the rest of the government.
It is understood that Mr Canney believed this was at odds with what was agreed in 2016, when the Government was formed.
Mr Canney had been appointed to the role for the first year of the minority Government and then was replaced by Mr Moran a year later.
However, with the Government set to enter its third year in office, Mr Canney thought the job should rotate again.
Last night Mr Canney stood up in the Dail with five TDs calling for a vote on a Government amendment to the Road Traffic Amendment Bill, which is being brought forward by his fellow alliance member, Minister for Transport Shane Ross.
As fewer than ten TDs were calling for a vote, the amendment was carried without a vote.
However Mr Canney's stance took members of the Independent Alliance by surprise as he is the Assistant Government Whip - a role which includes organising votes for the Government.
Seán Canny said it was always understood in the Alliance that he could oppose the Road Traffic Amendment Bill.
That piece of legislation is being debated in the Dáil again tonight.
Mr Canney may vote against the Bill in the Chamber this evening.
A meeting of the Alliance, that includes Mr Ross and Ministers of State Finian McGrath, John Halligan and Mr Moran, was set to take place yesterday was postponed until tomorrow.
The Independent Alliance has asked Seán Canney to clarify his decision within the group by the weekend.
However, it is likely that he won't reveal until next week whether or not he is staying in the Alliance.
It's understood that Sean Canney told Junior Minister John Halligan during a phone call earlier today that he is still considering his position.
There are unconfirmed reports that Mr Canney is to meet the Taoiseach Leo Varadkar later this evening.
Some sources are suggesting that Mr Canney, who is a chartered quantity surveyor, may seek some non-ministerial role at the Department of Housing.
