Anita's career as a legislator began in the Legislative Election (Pileg) in 2004. She was re-elected in the Pileg 2009 and made her way to the Senayan. Her political journey was briefly halted when she failed to advance in the Pileg 2014. However, Anita Jacoba Gah was able to return to the Senayan after being appointed to replace Jefirstson Riwu Kore, who resigned to run for the Mayor of Kupang Election in 2017. Anita then continued to serve the remaining term for the 2014-2019 period as a member of the Indonesian Parliament (DPR RI).

The moment Anita Jacoba Gah criticized Nadiem Makarim turned out not to be the first time it happened. In a working meeting of Commission X of the Indonesian Parliament with the Ministry of Education, Culture, Research, and Technology in 2022, Anita once again took a jab at Nadiem. At that time, Anita highlighted the issue of 400 people who attended as shadow teams at the Ministry of Education, Culture, Research, and Technology. "You may be proud of being applauded by the UN, but we are not, we are not proud at all," she said.
