It is expected to pass the house. The Supreme Court has said that states can't impose restrictions tougher than those put on Senators and Representatives outlined in the Constitution.
A proposal inspired by President Donald Trump's refusal to release his tax returns advanced Tuesday in Washington state. A bill in the state Legislature would require candidates to release five years of returns before they could appear on either the primary or general election ballot in the state.
Senators approved the bill on a 28-21 vote Tuesday, sending it to the House.
"Although releasing tax returns has been the norm for about the last 40 years in presidential elections, unfortunately we've seen that norm broken," said bill sponsor Sen. Patty Kuderer, a Bellevue Democrat, during debate Tuesday. Kuderer later confirmed she was referring to Trump.
How a candidate has handled their own financial affairs and personal investments are relevant details for voters choosing a commander-in-chief, Kuderer added.
