Shares of embattled electric vehicle start-up Nikola Corp. fell by as much as 17.4% during trading Wednesday morning after CEO Mark Russell failed to reassure investors that the company's $2 billion deal with General Motors would still go through and that ousted founder Trevor Milton wouldn't suddenly sell off his shares.

During an interview Tuesday on CNBC's "Mad Money with Jim Cramer," Russell said discussions with GM about supplying fuel cell and battery technologies as well as an all-electric pickup are ongoing, but he wouldn't comment much further than that.
