Two more staffers escorted out of Toronto Mayor Rob Ford’

More discord broke out in the offices of Toronto Mayor Rob Ford, where at two more staff members were escorted out of City Hall amid the fallout from allegations the mayor was videotaped smoking from a crack pipe.

CTV Toronto's Natalie Johnson confirms that the first man to be escorted from the premises was policy advisor Brian Johnston.

Johnston told CTV he was leaving on his own accord, adding that the "timing was right."

Johnston is the fourth staff member that has left the Mayor's Office amid the tension of Toronto's internationally-watched scandal, which stemmed from reports from Gawker and the Toronto Star that Ford was seen smoking from a crack pipe in a video being shopped to news organizations.

The video has yet to be made public, but Newstalk 1010 and the Toronto Sun have also confirmed they were told of the video before the scandal broke.

Ford's former chief of staff Mark Towhey was fired after reportedly urging the mayor to seek rehab, and last week press secretary George Christopoulos and his deputy Isaac Ransom resigned "on principle."

CP24's Stephanie Smyth tweeted that executive assistant Kia Nejatian has left the office as well.

Her colleague Katie Simpson reports that three more staffers had recently told media they were planning to leave their posts. It appears the exits of Johnston and Nejatian would bring that number to one.

It is getting very difficult to keep track of who remains active in the Mayor's Office, which was already working with a lean roster thanks to Ford's policy of keeping costs down.

The National Post's Megan O'Toole has done the world an immense favour by piecing together a chart of who remains. Check it out now while it is still somewhat up-to-date.

The turnover is coming quickly at this point.
