Did Elizabeth Warren lie to Congress?

At least on the first question Warren doesn't directly answer and provides an evasive answer. McHenry wasn't asking how she got involved but whether she had been involved.

After that, McHenry accused her of hiding the truth the last time she went before Congress, when she said bureau staff had provided advice to state officials negotiating a settlement with mortgage servicers that improperly foreclosed on homeowners.
A mortgage you can understand
McHenry pointed to a memo that the bureau put together on mortgage foreclosures that included a note that it was to go to Attorney General Tom Miller, the Iowa attorney general leading the talks with bank mortgage servicers. The congressman accused Warren of being a more central role in the talks than what she told a congressional panel in March.
But Warren responded that she was simply providing information requested by Treasury Secretary Tim Geithner, saying he had asked her to put the packet together for the Iowa attorney general. . . .

Reuters calls Warren a "consumer ally," but people need to understand that she is making loans more costly and thus raising interest rates. She might help out some who currently have loans, but at the expense of those who will be getting loans in the future. The other debate involved her unwillingness to stay longer to testify.

About an hour into the hearing Republicans sought to temporarily adjourn for votes. Warren objected to sticking around for more questions upon their return, saying her afternoon was packed with meetings and that the committee had agreed she would only stay an hour.

"Congressman, we had an agreement," she told Republican subcommittee Chairman Patrick McHenry after some back-and-forth.

"You had no agreement, you are making this up, Ms. Warren," McHenry responded. . . .
