Who is the current chair of the Joint Congressional Committee on Congressional Affairs?

you're a dick. stop commenting on other people's questions asshole.

There is no such thing.

There's no such committee, at least currently. There may have been a temporary committee with that name at some point in the past.

There is NO SUCH joint committee.

Joint Committees

The joint committees are made up of both senators and representatives. They typically have an oversight or policy role but no legislative duties.

[*] Commission on Security and Cooperation in Europe

[*] Joint Committee on Printing

[*] Joint Committee on Taxation

[*] Joint Committee on the Library

[*] Joint Economic Committee

While the Joint Committees on Printing and the Library have nominal responsibility for oversight of the Government Publishing Office and the Library of Congress, respectively, the committees are essentially defunct and oversight takes place within the majority party leadership of each chamber.
