On July 27, lawmakers elected on the platform of the Peoples Democratic Party (PDP), staged a walkout after Senate President Ahmad Lawan prevented Senator Philip Aduda from discussing the rising insecurity in Nigeria and an ultimatum was given to Buhari after a closed session.
The majority of senators are believed to have agreed that Buhari be given six weeks to fix security or face impeachment proceedings.
Speaking with reporters on Tuesday in Abuja, Kalu said the All Progressives Congress (APC) senators have the numbers to resist the impeachment move.
“The issue of impeachment is a non-existing issue. Nobody is talking about it. Even if they try it, they will fail because we have the number to resist it.
“There is nothing wrong with a lawmaker coming up with an impeachment threat, but will they succeed? No! As far as I am concerned, there is no discussion about Buhari’s impeachment.
“We have been meeting with the service chiefs and some of you were there and can testify that the issue of security has improved and it will keep improving,” Kalu said.
