<p>The continuing federal investigation of Macomb County Prosecutor Carl Marlinga focuses in part on campaign contributions he solicited for state Sen. Jim Barcia , the prosecutor confirmed Monday.</p>
<p>St. Clair Shores attorney Dennis Johnston raised or donated at least $2,000 to Barcia’s 2002 campaign at Marlinga’s request, Marlinga said in an interview with The Detroit News. Marlinga asked Johnston for the money because Marlinga had agreed to raise $2,000 for Barcia, who contributed $2,000 to Marlinga’s failed 2002 campaign for Congress.</p>
