He responded by saying there were four by his second wife, and indicated another child had been born to a former lover. Johnson declined to answer in a recent broadcast interview when he was asked how many children he has.Controversy surrounding Arcuri has threatened to blight Johnson’s Dec. 12 election campaign.
