ST. CHARLES, Mo. - When President Trump speaks in St. Charles Wednesday, he will make a pitch for the Republican tax plan, and he's expected to point to a small mom and daughter business as an example of whom it could help.

The Cassandra Erin Studio is a family-owned jewelry shop that employees five people and sells custom pieces to stores around the country. Everything is made in their store on Main Street in St. Charles.

The owners say the call from the White House was a surprise. Aids to the president told them they had researched the studio's website and wanted to use their story in the president's speech.

Mr. Trump is expected to say the Republican tax plan wouldn't just be good for large manufacturing businesses, but small ones, too. The owners of the studio, Cassandra Erin, and her mother Teri Sallee, said they'll be listening.

"We're interested. We want to know what's going on with our taxes," said Sallee. "If it can help, we're not political, we're artists. So we don't really know what any of it means, but this is the Show Me State — show me."

"My viewpoint is just trying to absorb and learn," said Erin of proposed changes to the federal tax code. "It gets kind of complicated."

Both women say they'll be happy for any exposure the president's speech provides.
