Yesterday, we gave you a financial update on the primary battle between CA Assemblymember Van Tran and OC businessman Quang Pham, but here's another recent development and the headline's not very good for Mr. Tran.  According to the OC Register, "Police Say Assemblyman Van Tran disrupted DUI Investigation".

Assemblyman Van Tran was so disruptive at the scene of the police investigation into Councilman Andy Quach's car crash that a sergeant had to threaten him with arrest to get him to stay away, according to incident transcripts released today by the police chief.

Tran said today that he was at the scene because Quach called him and asked that he come, but said he did not interfere in any way.

The Westminster councilman early Sunday morning clipped another car and crashed into a power pole, knocking out power to about 300 homes in his city. Quach has since been charged with misdemeanor drunken driving and driving with a blood alcohol of over 0.20 percent. His blood alcohol at the time was 0.26 percent – more than three times the legal limit.

According to the article, the new information was released after pressure from bloggers:

Bloggers have also asked why information about another vehicle was not released earlier. They have also raised questions about whether Quach was the sole occupant of the black Mercedes or whether Tran was riding with him.

Police Chief Andy Hall said he wanted to clarify those issues by releasing transcripts of the incident and giving a detailed account of how his officers handled the case.

When asked about the incident, Pham's campaign says he he will not accept any interview requests. “I was not there so I have no comment,” said Pham, “Let the legal system run its course.”

Both men are in an uphill battle to unseat Democratic Congresswoman Loretta Sanchez.
