A senior CIA analyst resigned Tuesday amid accounts that she had been pressured to step down after her husband — a former agency employee — was charged with leaking classified information to the press.

Heather Kiriakou had served as a top analyst on some of the most sensitive subjects that the agency tracks, including leadership developments in Iran. Her husband, John, faces a maximum of 30 years in prison after being accused of disclosing details about secret CIA operations as well as the identities of undercover officers.

Two sources in direct contact with the Kiriakous said that Heather had submitted her resignation under pressure from superiors at the CIA. She had been on maternity leave in recent months. Neither she nor John Kiriakou returned a phone message left at their home.

“They told her to come in and resign,” said one person with direct knowledge of the Kiriakou case. Both sources spoke on condition of anonymity, citing the sensitivity surrounding Heather Kiriakou’s employment status and the pending prosecution of her husband.

CIA spokeswoman Jennifer Youngblood declined to comment, citing “respect for Ms. Kiriakou’s privacy.”
