The probe will focus on pay-for-play schemes and tax code violations, according to law enforcement officials and a witness who wishes to remain anonymous.

The officials, who spoke only on condition of anonymity, said the probe is examining whether the Clintons promised or performed any policy favors in return for largesse to their charitable efforts or whether donors made commitments of donations in hopes of securing government outcomes.

The probe may also examine whether any tax-exempt assets were converted for personal or political use and whether the Foundation complied with applicable tax laws, the officials said. –The Hill
