Here's something I don't understand. Conyers and the Judiciary Committee subpoened Sara Taylor, who used to work in the White House. Her lawyer wrote Conyers a letter saying she wants to testify, but the White House won't let her.
How can the White House not let her? She wouldn't be breaking any law, she no longer works for the White House, and Bush and Cheney are not her mama. What are they planning to do about it if she does testify?
Her testimony would be in regard to the U.S. attorney firings.
I don't know of any precedent for "not letting" a former employee testify, or under what authority such action can occur. The situation was revealed this morning on ABC's "This Week" in a question the show's host George Stephanopoulis asked Conyers, Chair of the House Judiciary Committee.
Coyers hinted that impeachment of Bush and Cheney is getting to be more of a real possibility because of their stonewalling of various congressional investigations.
