The home of the Integration Minister was targeted by a group of protestors last night.
Banners reading 'South Dublin Says No' were attached to railings outside Roderic O'Gorman's home in west Dublin.
The banners also called on him to 'Close the Borders'.
A video posted on social media shows a number of people standing outside.
Gardaí have confirmed they maintained a presence until the group dispersed but say they do not comment on the security arrangements of any individual or group.
Labour Justice Spokesperson Aodhán Ó Ríordáin told Newstalk Breakfast the targeting of politicians needs to stop.
"I'm running in the European elections and this has already been the most poisonous, the most abusive campaign I have ever been involved in - and I'm doing this 20 years," he said.
"Something has changed, there's been definitely a turn in the way that people interact with each other.
"I have deep worries for the direction that politics is going".
'Important to dial it down'
Deputy Ó Ríordáin said parties are finding it difficult to get people willing to run.
"All political parties are finding it difficult to get people to stand," he said.
"Every political party will talk to each other and say, 'We can't get candidates to run in the local elections' and this is the reason.
"How we interact with each other in the political sphere is important to dial it down."
Deputy Ó Ríordáin said those involved in 'whipping up' issues need to reflect.
"This sort of thing of going to individual's houses: if it's politicians today it could be teachers tomorrow, it could be Guards the day after," he said.
"It could be anybody who's a figure of authority or influence in any community.
"Those involved in this need to step back but those who whip this stuff up need to reflect on what they're saying and the influence they're having," he added.
Protestors have previously gathered outside the homes of Simon Harris and Leo Varadkar which were widely condemned.
