What did we learn from former President Donald Trump's speech at the RNC? One word: tariffs.

"It's not surprising to anyone that Trump likes tariffs...you could say the same about JD Vance" says Yahoo Finance’s Washington Correspondent Ben Werschkul.

The so-called trade war was a big part of Donald Trump's first term in the White House; the subsequent Biden administration kept most of the tariffs he imposed in place.

"It's an area where a president can act unilaterally" Ben adds, suggesting the Trump-Vance ticket would likely "reinforce their instincts on this if they get elected".
