Helloworld Travel (ASX:HLO) CEO Andrew Burnes released a statement yesterday denying he organised meetings with Russell Carstensen and Joe Hockey.
In the statement it said: "I emphatically deny ever having told Mr Carstensen that Mr Hockey “owes me” or any words to that effect".
Labor had questioned whether Hockey, Australia’s ambassador to the US, had used his position to help a company for his personal benefit.
Mr Hockey was a shareholder in Helloworld, which holds the Whole of Australian Government (WoAG) accommodation and travel contract, at the time of the April 2017 Washington meeting.
The allegation was tabled at a Senate estimates hearing on Thursday afternoon.
Shares in Helloworld Travel (ASX:HLO) closed 0.58 per cent lower to $5.17 yesterday.
