In the wake of Hadia Tajik's resignation in March 2022, Brenna was floated as a possible successor, and was so again in December the same year. In February 2023, both Troms and Akershus county chapters chose her as their preferred candidate for the national party's deputy leader. Brenna thanked for the confidence and said that she was willing to take on the role if that's the party wish for at the party conference in May. She officially announced her candidacy on 1 March. On 21 April, the party election committee announced that they would designate her as one of two deputy leaders, alongside Jan Christian Vestre. She was formally elected during the party conference in May.
In her capacity as deputy leader, Brenna was also charged with crafting the Labour Party's policy program ahead of the 2025 election, which she public presented a draft of at the end of September 2024.
She was a political advisor at the Office of the Prime Minister from 2012 to 2013. During this time, the 22 July commission was handed over.

She was elected as a regular representative to the Storting from Akershus at the 2025 election. She also succeeded Bjørnar Skjæran as the Labour Party's parliamentary leader and joined the Standing Committee on Foreign Affairs and Defence.
On 14 October 2021, she was appointed minister of education in Støre's Cabinet.
Brenna expressed that the Solberg Cabinet's early re-instalment of school absence rules were wrong. She promised to be back with a better solution as soon as possible, saying that rules had to be understandable for both teachers and students and to be experienced as sensible.
Following demands for the absence limit in upper secondary schools to be relaxed, Brenna announced that this change would become effective on 5 November and last throughout the school term. The primary cause for the demand had been that students should not be given absence remarks due to having COVID-19 and have the need to go into quarantine. She said she understood the dilemma for students, and noted that they would have to get an approved leave of absence, to for example go to a doctor's appointment or similar.
On 17 November, Brenna ordered the Norwegian Directorate for Education and Training to halt the case process of private schools. Brenna said that the government wanted to strengthen public schools and wanted to stop the previous government's privatisation of schools. The Conservative Party's Margret Hagerup called it "a dark day" for Norwegian students, and that the government had focused on "ideology and structure" instead of "quality and diversity".
In early December, Brenna expressed that private schools earned to much from students taking private exams. She stressed that upper secondary schools should advise students better and to inform them of their choices when it comes to higher education. She did however add that private education isn't necessarily bad, and serves as "a safety valve" for those who don't have other options.
