Sources said the RS Secretariat has sent a letter to Prachi asking her to explain the controversial "terrorists in Parliament" remark against MPs.
A number of MPs had moved a privilege notice and asked Chairman Hamid Ansari to proceed against her. The sources said the secretariat has sought her comments before proceeding any further on the privilege notice.
Leader of the Opposition in Rajya Sabha Ghulam Nabi Azad, CPI(M) MP Sitaram Yechury and TRS member K Keshav Rao were among 20 members who had given the privilege notice against Prachi saying her remarks had "violated the dignity" of Parliament and privilege of MPs.
"It is a big misfortune that in the Indian Parliament, we have one-two terrorists sitting there. I do not think there can be a bigger misfortune for India than this as they who, are disobeying the judgement of a court, because the court has proved that he (Yakub) is a terrorist. When the court has already proved so, those supporting the terrorist are terrorists themselves I believe," she had said.
