[1][2] In June 2020, she announced her candidature in the 2020 Hong Kong pro-democracy primaries, in which she obtained a nomination ticket in the general election that was later postponed.

She interviewed a young pro-democracy activist who expressed solidarity with other Hong Kong protesters, which garnered Ho a lot of attention for her reporting.

[22] On 18 June 2020, Ho announced her intention to run in the (subsequently postponed) 2020 Hong Kong legislative election after quitting her journalism career.

[24] On 6 January 2021, Ho was among 53 members of the pro-democratic camp who were arrested under the national security law, specifically its provision regarding alleged subversion.

Friends of Ho have posted on her social media pages several long letters from jail in which she interweaves her political stance, pop culture and the future of the pro-democracy movement.

[27] On 9 December 2021, a Hong Kong court found Ho guilty of inciting and taking part in an unlawful assembly on occasion of the 31st anniversary of the 1989 Tiananmen Square protests and massacre on 4 June 2020.

[28] During the trial, Ho said while she had been in Victoria Park on the evening of the candlelight vigil, she had not been taking part in it, but instead intending to show resistance to the regime; and that her holding flowers and a candle was to test the difference between Hong Kong and mainland China.
