Sweeney is a former art and design lecturer from Letterkenny. She has worked as a community activist and volunteer. She was involved in the Donegal Pro-Life campaign during the referendum on repealing the Eighth Amendment.

Our party Aontú is built on the basis of restoring truth and honesty to Irish politics. I am a woman with a record of successful campaigning on issues important to the people of Donegal.

Tackling the reduced health services in Donegal, especially the massively understaffed mental health services. Activate services that exist in every other acute hospital, like stroke and prostate units, which are not available in Letterkenny University Hospital.

I want to establish a task force to address mismanagement in the health service and to immediately employ people for the unstaffed stroke and prostate units in Letterkenny Hospital.
