(Portland, OR)  --  Multiple reports say Portland Public Schools Superintendent Carole Smith was informed in March about lead testing in schools, despite saying she didn't know about the test results until late May.  KGW-TV reports Smith's chief of staff, Amanda Whalen, forwarded her boss emails that outlined the plan to test drinking fountains and sinks at Rose City Park Elementary School.  One email said the results should be available by the week of April 4th.  The school district has been a center of controversy since tests at Rose City Park and Creston schools showed high levels of lead at some sinks and water fountains.
