Donald Trump's re-election campaign has reportedly raised nearly $500,000 by selling plastic straws branded as an alternative to “liberal paper straws.”

The US president's 2020 campaign manager, Brad Parscale, said they had to re-stock the merchandise after selling out with their first several thousand orders.

The red, BPA-free, recycling friendly and reusable straws are made in the US, come in a pack of 10 for $15 (£12) and are laser engraved with "TRUMP" in block capitals.

“Liberal paper straws don’t work. STAND WITH PRESIDENT TRUMP and buy your pack of recyclable straws today,” the product description states on the re-election campaign website.

Mr Parscale said last week the campaign store had sold more than 140,000 straws and raised over $200,000 in sales - just days after they went on sale. That figure is now close to half a million dollars, he said in a tweet.
