Rooney, who rejoined his boyhood club Everton from Manchester United in July previous year, scored 11 goals in the first half of the campaign but has failed to nail down a starting place under manager Sam Allardyce.
DC United boss Ben Olson has confirmed interest in Wayne Rooney but insists the deal to take him to MLS is not yet done.

"Certainly the deal is not done, but obviously there's some interest from our end", said Olsen, who seemed surprised to be tackled on the topic by celebrity news website TMZ as he walked through an airport.
The 32-year-old scored 11 goals in the first half of the campaign but has struggled for consistent game-time under Toffees chief Sam Allardyce recently. He joined the Goodison Park outfit on a free transfer last summer after spending over a decade at Old Trafford, but has found it hard to make an impact with Everton.
"But in terms of clarity of whether Wayne is staying or leaving, I'll find out a little more later when he comes into training", the former England manager added.
Allardyce, who has had a troubled relationship with Everton's fans, who are unhappy at his style of play, said: "Wayne is a special player but if any player wants to leave they can, in my opinion".
"Wayne is the leading goalscorer but quite a few of those are penalties so that is the main aim if you are going to finish higher in the league".
"But if he does choose to go on I just need to wish him all the best really, him and his family".
"It's a tricky question for me to answer", Allardyce said.
"There is an area we need to improve and that is goals".
