In 1982, John Lakian ran for the Republican party nomination for governor. He was the early favorite after securing the party's endorsement.^[4] Lakian spent nearly $1 million on his failed bid.^[5] After a The Boston Globe story revealed that he had made several exaggerations about his background, he was forced to publicly confess and lost the nomination to John W. Sears. Supporters blamed the loss on The Globe, claiming it had unfairly defamed Lakian.

As a result, Lakian sued The Globe for libel, claiming $50 million in damages.^[6] The court case drew national media attention and eventually resulted in The Globe being cleared of all charges.^[7] The jury found that the article contained some false information, but awarded no judgment, stating that Lakian had failed to prove any actual harm. Lakian appealed and the case was finally resolved in 1987 when the Massachusetts Supreme Court rejected the appeal.^[8]

Lakian returned to politics in 1994 to challenge Mitt Romney for the Republican nomination for U.S. Senate. Lakian outspent his rival but was defeated by Romney who won the nomination.^[9]

On Friday, February 5, 2016, John Lakian pleaded guilty to two counts of securities fraud for defrauding investors out of millions of dollars in two separate schemes. When sentenced, he faces a maximum sentence of 20 years' imprisonment on each count.

Between 2009 and 2013, John Lakian and his partner Diane Lamm were involved in two schemes to steal investors' money. In the first, the defendants obtained more than $11 million by promising Capital L investors that their money would be used to purchase, consolidate, and sell registered investment advisory businesses. Instead, Lakian and Lamm diverted more than $3 million of it to themselves and to entities they owned and controlled. In the second scheme, the defendants perpetrated their fraud through their management of the liquidation of Aegis Capital, a North Carolina-based investment fund. Instead of returning investment proceeds to investors, Lakian and Lamm diverted more than $2 million of investors' money to themselves and to restaurant businesses they controlled.^[10]

Capers, United States Attorney for the Eastern District of New York, "The defendants played a confidence game, stealing investors' hard-earned money through lies and deceit to use for their own purposes".
