Niguse was known for being critical of the
TPLF government and especially argued against the integrity of the
regional election held in 2020. His most notable political contribution was popularizing the Fenkil Tigray Movement by using
social media. His method of spreading awareness of Fenkil was especially successful amongst youths. Fenkil's political objective was to, "free Tigray's people from the pressure of TPLF ... spreading across many towns in the Tigray region." In July 2020, four months prior to the start of the
Tigray War, as leader of the Fenkil Movement, Yemane criticised the TPLF for what he said was the recruitment of Tigrayan youths into military training on false pretences. According to Yemane, the youths were given promises of land that were not fulfilled, and the TPLF claimed that the
Ethiopian National Defense Force (ENDF) and the
Eritrean Defence Forces (EDF) were planning to attack Tigray Region. The TPLF claimed that the Fenkil Movement was supported by the
government of Eritrea. ==Assassination==
