(Olympia, WA)  --  A bill that's aimed at making it easier for landlords to rid their properties of squatters is moving through the Washington Legislature.  The GOP-led Senate voted along party lines, 26-23, to advance the bill, which would require officers to remove squatters on grounds of criminal trespassing.  Democrats say the bill could negatively impact tenants who don't have written lease agreements, but instead have verbal agreements to stay on a property.  The bill's sponsor, Representative Hans Zeiger, says he's willing to narrow the scope of the measure to gain bipartisan support.
