OMAHA– Warren Buffett will not limit the scope of questions he is asked at this weekend's annual meeting of his conglomerate Berkshire Hathaway (BRKa.N), the iconic investor told Fox Business on Thursday.

Buffett was asked if he would restrict questions in light of the ongoing scandal over former Berkshire executive David Sokol. He said he would not.

Berkshire's board released a report this week accusing Sokol of misleading the company and suggesting he may have violated the law in connection with his investment in Lubrizol Corp (LZ.N), a company he suggested Buffett acquire after buying $10 million worth of its stock.

Buffett is expected to face one of his toughest grillings ever at this year's meeting, which will draw tens of thousands of investors to Omaha on Saturday.
