"If Taslimuddin wishes to join JAP the party will welcome him," Yadav, who was expelled from RJD, told reporters.
RJD had showcaused Taslimuddin on May 22.
"Why action is being taken only against Taslimuddin and not against Raghuvansh Prasad Singh who has also been making statements against Nitish Kumar?" the Madhepura Lok Sabha MP asked.
He said it was an "old habit" of RJD supremo Lalu Prasad and CM Nitish Kumar to make "scapegoat of leaders due to whose hardwork they came to power".
"If he (Shahabuddin) is not involved in the journalist's murder than why Nitish Kumar government is harassing him?" he asked.
