Partly Facetious: How could you bar a federal minister?

"I was appalled at the treatment."
"I agree, I mean Fawad Chaudhry is a federal minister and to be barred from attending the Senate just because he verbally attacked Mushahidullah, whose personal contributions to PIA and PSM's finances have been significant, as well as his comments that rival FC's..."
"Are you being facetious?"
"Yes I am, and I support FC because he says it like it is though I agree he needs to work on how to say the same thing with a poisoned barb rather than acting like a Spitting Cobra that spews poison..."
"A spitting cobra attacks one person at a time."
"In Kenya a spitting cobra is around 9 feet long and can kill 20 people."
"Ha, ha, indeed there has never been one like FC then, because his predecessors - take Zardari sahib's Kaira and Firdous Ashiq, the lady who is now in the PTI, or take PML-N appointed Parveen Rashid, who was sacrificed and along came Marriyum Aurangzeb and none of them would take on more than one, maximum two, at a time - and here is FC taking on so many and for good measure he also took on Chairman Sanjrani, you know the man PTI supported because he was from Balochistan......"
"The Khan has come of age - our previous heads of government took umbrage, serious umbrage, at anyone daring to challenge those they selected for whatever position ... oh and when will you get your key board sorted out; its Parvez Rashid not Parveen..."
"As soon as the British government renames Middlesex country!"
"Oh shush, anyway I am saddened that when I said I was appalled by the treatment you thought I was referring to the FC case. No my friend I was referring to the initial refusal of the Afghans to hand over SP Tahir's body..."
"A fitting response is called for; I reckon this is our 9/11. We must not be compelled to overlook this incident and carry on we support Afghanistan's efforts towards peace with the Taliban and the peace must be Afghan led and Afghan driven because clearly they do not want to have peace with us..."
"Right and Prime Minister Khan if you keep a portfolio then you have no deniability! Remember Mian Nawaz Sharif keeping the foreign affairs portfolio and then that Indian industrialist came into the country without a visa and he never ever spoke about Kulbhushan which you Mr Khan as a politician rightly milked for all it was worth..."
"I agree, this is the time The Khan needs to address the nation, a nation angered at the treatment meted out to one of its sons, a nation in mourning..."
"We voted for you Mr Khan, please be different."
