The US Solicitor General is the representative for the US Government in cases that come before the US Supreme Court, nothing more nothing less.
They will either argue the case that's brought by and for or against the US, or they will file amici curiae briefs on behalf of the US government in cases in which there are special interest or concerns of the US government.
The Solicitor General is in no way characterized as the President's own lawyer.
That would be the White House Counsel. Currently Greg Craig , with a staff of "Deputy Counsels and Special Counsel, Associate Counsels, Deputy Associate Counsels, Research Director, and Staff Assistants and Administrative Assistants".
President Barack Obama said, "The White House Counsel’s office is tasked with making sure that we are operating under the highest standard of ethics and transparency for the American people. "
Sounds like they should putting the long form birth certificate on the White House website.
ROFLMAO!
BTW, one of those Deputy Assistant Counsels is one Rashad Hussain, 2003 Soros fellow, who says in his biography that says in his biography that he "finds his heritage central to his identity as a Muslim American and his career goals, especially in light of events in recent history," namely 9/11.
