The Tánaiste has said he thought a controversial letter from the CEO of Dublin City Council to UCD's Students' Union was a Waterford Whispers article.
Owen Keegan responded to concerns the union had about purpose built student accommodation by saying they should become property developers themselves.
He also said it wasn't the city council's fault the Students' Union didn't know how planning applications work.
Tánaiste Leo Varadkar has joined Taoiseach Micheál Martin in saying the letter should be withdrawn.
"He shouldn't have written that letter, quite frankly.
"I don't want to slag him off, he's a capable manager and he's done some very good things.
"But when I saw that letter I thought it was Waterford Whispers to be honest, I didn't really think he actually wrote that letter and signed it.
"I thought it was kind of insulting, actually."
