A former LVCVA executive hid the purchase of $90,000 in Southwest Airlines gift cards in records at the agency. Brig Lawson, the senior director of business partnerships, said the money was for promotional events and did not disclose that it was for gift cards. Lawson also instructed Southwest employees to submit invoices without mentioning the purchases were for the cards. More than $50,000 of the cards cannot be accounted for. The convention authority is publicly funded . Lawson recently resigned.
