The senators on Wednesday, March 15, during a plenary unanimously passed a motion to issue the warrant that will compel Ali appear before it on Thursday, March 16.
The Senate decision came after Ali failed to make an appearance before the Red Chamber today.
He had in a letter told the Senate that he (Ali) would not be able to appear before it because he was bereaved.
The customs boss had in recent time had series of altercation with the Senate after the senators said he (Ali) must appear before them dressed in a custom's uniform.
However, Ali, a retired Nigerian army colonel in his response said will not wear uniform as he was only appointed to work and reform the Nigeria Customs Service.
