LEE COUNTY, Fla.- The Lee County Attorney's Office tells WINK News it has asked KRAFT Contracting, the contractor on the Ortiz jail expansion project, to turn over all of the documents it has for the 25 arrested workers.

While only one actually worked for KRAFT, according to the county contract, KRAFT is responsible for making sure all of the workers are legal, including its sub-contractors.

President and COO of Kraft Construction John Pinholster says at no time did they knowingly hire illegal workers. We asked him about the one KRAFT employee arrested on Thursday.

"In fact it turns out he was in fact here illegally working here for us and that his documents were fraudulent and it's my understanding he is being deported," said Pinholster.

But, short of doing I guess extension federal background checks, I don't know what else to do," Pinholster went on to say after we asked what else can be done to make sure this does not happen again.

In 2007, KRAFT signed an agreement with Lee County saying it will not use illegal workers on the jail expansion project, this includes its sub-contractors. All contractors are now required to do so when entering into the bidding process with Lee County.

Most of the 25 arrested on Thursday worked for sub-contractors, including Spectrum Contracting.

Spectrum also tells WINK News it did not knowingly hire illegals.

"Everything is on file, everything is documented, we are definitely in compliance," said Bob Valentine with Spectrum Contracting.

If immigration determines the workers were here illegally, they broke the law and will be deported.

The County Attorney's office says it will review the documents for all 25 and determine whether the companies knowingly hired them and if it finds the companies did, it has the right to cancel the contract.

We are told the arrests should not impact the completion of the expansion project.

KRAFT says it reminded all of its employees and sub-contractors Friday of its policy that all workers and documents must be legal.

Immigration and Customs Enforcement would not release the names of the other companies involved because the investigation is ongoing.
