(Olympia, WA)  --  A Washington state senator from Lynnwood is working on a way to force President Donald Trump to release his tax returns.  Senator Marko Liias says he's looking to find out whether Trump's name can be kept off the ballot in Washington state if he continues to withhold his returns.  Liias says he's contacted state Attorney General Bob Ferguson to find out whether failure to release the returns can keep Trump off the ballot in the state of Washington, or give the state authority to withhold its 12 electoral votes.
