Former Speaker Newt Gingrich is dramatically scaling back his presidential campaign, according to news reports.

The Georgia Republican will cut one-third of his staff and has already replaced campaign manager Michael Krull with deputy campaign manager Vince Haley.

The campaign will also refocus its strategy around persuading delegates to the August convention in Tampa, Fla., to support him, according to multiple news reports.

Gingrich’s campaign has been struggling in recent weeks. He finished third in the recent Louisiana primary and fourth in Illinois and hasn’t won a state since his native Georgia earlier this month.

In addition, his fundraising efforts have been less successful in recent weeks, and a super PAC supporting him has run out of cash.

Gingrich is scheduled to speak at Georgetown University on Wednesday.
