A federal judge has ordered the State Department to hand over records detailing Hillary Clinton's schedules during 14 overseas trips as secretary of state amid speculation that Clinton kept meetings with donors to her family's foundations off her official calendar.

In a Freedom of Information Act lawsuit filed by Citizens United, the court moved to compel the State Department to produce emails sent to and from Lona Valmoro, a Clinton aide, regarding overseas trips where unreported donor activity was suspected.

The conservative group had obtained correspondence from the State Department that suggested Clinton may have met with donors to the Clinton Foundation while on diplomatic trips.

Huma Abedin, Clinton's former chief of staff, raised eyebrows when she obtained a personnel waiver that allowed her to collect simultaneous paychecks from the State Department, the Clinton Foundation and a well-connected consulting firm called Teneo Strategies.

Abedin kept control of Clinton's schedule and often determined who would get face-time with the secretary.

During a trip to Ireland in 2012, Clinton met with executives from Teneo and attended an event hosted by a Clinton Foundation donor, emails provided to Citizens United show.

But a planned dinner in Dublin with Teneo executives never appeared on her official calendar, raising questions about whether the gathering was struck from her schedule for political reasons.

"Citizens United wants to know how many overseas dinners Sec. Clinton attended with Clinton Foundation donors that didn't make it on her schedule," said David Bossie, the group's president.

A lawsuit filed by the Associated Press has also turned up evidence that Clinton's official calendars omitted dozens of donor meetings.
