Senate Majority Leader Harry Reid's (D-Nev.) new chief of staff is a heavy-hitting Democratic donor, who's contributed at least $35,000 to Reid himself.

David Krone, a former Comcast executive and telecommunications lobbyist whom Reid tapped as his new top aide, is the largest single individual donor to Reid, according to an analysis by the nonpartisan Center for Public Integrity.

Krone has donated more than $35,000 to Reid's campaign and the top Senate Democrat's political action committee, the Searchlight Leadership PAC, according to Federal Election Commission records.

Those records show thousands of dollars in donations to other Democrats over time, including a variety to senators and candidates for Senate, along with a smattering of donations in House races.

Krone joined Reid's office in 2009 and has served as deputy chief of staff before his elevation.

"David’s experience in the private sector and commitment to public service will serve him well in this role as Chief of Staff," Reid said in a statement announcing Krone's appointment. "I am confident that he will be a tremendous leader for my office and a great resource for our caucus.”
