Update 12.25 hours: The Labor party has joined the growing call for mass demonstrations to protest against Donald Trump's visit to Ireland.
Two cabinet ministers Finian McGrath and John Halligan have also stated their opposition to the visit, as well as People Before Profit.
The government says that Mr Trump's visit will be an "opportunity to respond to the issues discussed in the White House in March, such as migration, trade, climate change and human rights".
Labor leader Brendan Howlin says that this will be a call for people who are against the world view of Donald Trump.
"Ireland is an open and tolerant nation, committed to peace and democracy, the values of Trump are not our values and there would be no welcome for this man," he said.
"We have to send a clear signal about the world that dangerous politicians are being thwarted by all democratic means, including through peaceful protest.
"Labor will actively oppose this visit and work with like-minded people.
"I would like to ask people to commemorate the protests in 2003 against the war in Iraq, where more than 100,000 people marched in opposition. Now is another time when people from all walks of life have to raise their voices together.
Earlier: Richard Boyd Barrett: & # 39; Shameful & # 39; that Donald Trump visits Ireland
Update 7.05 hours: People Before Profit TD Richard Boyd Barrett made the decision of the Taoiseach to welcome Donald Trump as "shameful" in Ireland.
He says he has already contacted other groups to organize big demonstrations when the US president arrives in November.
He says his politics have made the world more dangerous and divided.
Deputy Boyd Barrett says he does not like what Mr. Trump stands for.
"Donald Trump is a promoter of the politics of hatred, of greed, of war and of prejudice and I find it really shameful that Leo Varadkar would bring him here to legitimize and empower that policy.
"I really want people who believe in peace, equality and justice to come out and protest against Trump's really bad political agenda."
