Today, Republican Norm Coleman is expected to rest his case to overturn Democrat Al Franken’s lead in Minnesota’s U.S. Senate race.

Over the past six weeks, Coleman’s attorneys have worked to present many, sometimes sprawling, reasons why Franken’s 255-vote lead is “artificial.” They’ve spent dozens of hours presenting hundreds of rejected absentee ballots they say should be counted into the race, showed examples of the different ways different counties treated absentee ballots and sought to prove that some votes were counted twice in the state’s two-month recount.

Today, after Minnesota elections director Gary Poser and Minneapolis election judge Pamela Howell testify, Coleman will bring his case to a close.

Howell will be allowed to testify in the U.S. Senate election trial — but Coleman will have to pay for the delays caused by his attorneys’ mistakes in disclosing documents about Howell.

Howell began testifying in the trial last week, but stopped after it was revealed that Coleman’s attorneys violated the rules of civil procedure because they didn’t give Democrat Al Franken’s attorneys certain information about her.

Last week, the judges had barred her from testifying because of the problems, changed their minds and were willing to allow her to testify on Friday. But once she began her testimony, she revealed that there were more documents that the Coleman attorneys neglected to share.

The judges today decided to allow her to testify but also decided that Coleman would have to pay for the costs of the delay that his attorneys’ nondisclosure caused.

Next, Franken will present his case that his lead should stand and even be increased. Franken’s attorneys are slated to start that presentation Tuesday.
