Now Playing: Trump administration says it won’t spend $1 billion on solar farm Now Playing.

Now Playing Trump administration warns against ‘overreaching’ on border Now Playing President Donald Trump will sign an executive order Thursday to put an end to Obama-era policies that have restricted solar and wind energy development on the United States’ southern border.

Trump will unveil the solar farm in Arizona’s Apache Junction, which is one of the most productive solar energy installations in the country.

Trump is expected to sign the order Thursday afternoon, according to a senior administration official who spoke on condition of anonymity to discuss private conversations.

The official said Trump will send the order to the Environmental Protection Agency, which regulates the solar industry.

The order is expected in the coming days, the official said.

The Trump administration has argued that the solar policy is meant to encourage more solar development and has blocked the expansion of wind and solar farms in Arizona.

In a speech to the solar community last month, Trump said he was working on a “solar policy that is smart and sustainable and that helps people,” adding that he would make a decision on the issue soon.
