Data on millions of US President Donald Trump’s supporters is up for rent for GOP candidates and conservative groups ahead of the November midterm elections.

Consultants close to the president are offering a list with the email addresses and cellphone numbers of millions of people even to businesses.

“Republicans have suffered from being behind in small-dollar fund-raising, and the president, over the course of the campaign and his presidency, has built the largest Republican first-party data list,” Trump campaign manager Brad Parscale told The New York Times on Saturday.

Data from Hillary Clinton’s 2016 presidential campaign was similarly sold to the Democratic National Committee for $1.65 million in 2017.

“So giving other candidates and groups access to that data through a legal means to rent it was one of the best things I could do for the Republican ecosystem. And the campaign makes a little money, too. It’s a win-win,” Parscale added.

Trump’s campaign previously signed a contract with Excelsior Strategies, to rent its list at the rate of $35 per 1,000 addresses.

Boarding Marine One to head a political rally in Kentucky on Saturday, President Trump told reporters that he is reminded of the year 2016, as the 2018 midterms approach.

“There’s something going on,” he said. “This reminds me of ’16. It reminds you of ’16, too.”
