The Trump administration has rolled out a new regulation freezing wages for foreign guest workers on U.S. farms until 2023. After that, most guest workers would see smaller pay increases than they would have under the current system, potentially lowering their earnings for years to come.

The change would be a boon to growers and a major setback for the low-wage farmworkers who have been classified as essential during the pandemic. The administration projects the change would save agricultural employers $1.68 billion over 10 years by allowing them to pay workers lower minimum wages under the law.

One operation that could benefit directly from the new policy is the Trump familys vineyard in Charlottesville, Virginia, which has employed foreign workers on H-2A visas in the past. The presidents second-eldest son, Eric Trump, owns Trump Winery.

Workers on H-2A visas come from Mexico and other countries to work temporarily on U.S. farms. H-2A employers must pay them a prevailing wage that the government determines known as the Adverse Effect Wage Rate (AEWR) so they dont undercut the wages of U.S. workers.

If the new regulation goes into effect, employers like Trump Winery may not have to increase their pay rates for H-2A workers over the next two growing seasons, even though they likely would have under the status quo. After 2023, most farmworkers are likely to see smaller pay boosts because the administration wants to change the source that determines the wage rates.

The proposed regulation serves as a reminder of the endless thicket of conflicts of interest the Trump presidency has created. The Trump familys extensive business dealings in the U.S. and around the world could factor into countless policy decisions coming from the executive branch.

HuffPost asked the Labor Department if it was concerned about the conflict of interest such a rule creates for the White House. A spokesperson had not commented as of Tuesday afternoon.

Jordan Libowitz, a spokesperson for Citizens for Responsibility and Ethics in Washington , a nonprofit ethics watchdog, said its natural to question the motives in any decision the Trump administration makes regarding work visas. The presidents Mar-a-Lago property also avails itself of guest workers , who are hired on H-2B visas.

This is a thing that could clearly benefit the family business, Libowitz said. This is the whole problem with having a president with a bunch of businesses connected to his name. Every decision made by his administration, made by the government, has to be looked at through this lens.

Businesses that want to use H-2A workers have to petition the government before they can hire them. Trump Winery sought to bring on 23 such workers in 2019, according to Labor Department data . The winery proposed paying them $12.25 the minimum pay required at the time under Virginias AEWR.

Donald Trump scooped up the winery and estate in 2012 at a bargain price of $6.5 million, then either sold or gave it to Eric, according to the New York Post . The winerys website says the business is a registered trade name of Eric Trump Wine Manufacturing LLC, which is not owned, managed, or affiliated with Donald J. Trump or any of his affiliates.
