EFF criticises Parliamentary inquiry
The party's representatives on the committee stormed out soon after the hearing resumed.
The hearings are taking place in the absence of EFF leader Julius Malema and his fellow MPs who've dubbed the proceedings 'a kangaroo court'.
The MPs are charged with being in contempt of Parliament by breaking the rules when President Jacob Zuma's question and answer session was disrupted on 21 August.
National Assembly Speaker Baleka Mbete had to ajourn the sitting of the house.
EFF MP Lucky Twala asked why the committee was about to hear closing arguments when Minister of State Security David Mahlobo and Telecommunications and Postal Services Minister Siyabonga Cwele had not yet testified.
"That for us is problematic. How do you arrive at a conclusion without having heard all the evidence?"
Committee chairman Lemias Mashile insisted members had agreed in a meeting behind closed doors last week that the minister's absence on foreign trips would not hold up proceedings.
An angry Twala and fellow MP Abner Mathloko then left the meeting.
Eyewitness News understands other opposition MPs are also unhappy with the process.
