Interestingly enough, Baker chose as his attorney, Abe Fortas, longtime friend of LBJ. Fortas would later be appointed to the United States Supreme Court where he gained "fame" as the first justice to ever resign under pressure.
Fortas quit being Baker's attorney just after the assassination because he took a new post. The following is an excerpt from a November 26, 1963 memo from then Texas Attorney General Wagoner Carr:
Mr. Fortas informed me that he has been assigned to coordinate the FBI, Department of Justice and Texas Attorney General's efforts regarding the assassination of President Kennedy.
It appears that Fortas was another attempt to control the investigation, since the memo in question is dated prior to LBJ's creation of the Warren Commission.
Do YOU see a pattern here?
Johnson, who had suffered a major heart attack in the mid 1950's, was also well aware that his health would probably not allow him to run for the presidency in 1968, his next possible attempt. With his own state political base in disarray, he had only one potential path into the White House: succession. He had also become financially dependent on his inner circle of businessmen-friends, whose support was and had been, vital to both LBJ's political career and his wallet. Many have said that no one ever profited, wealth wise, more from the Presidency, than did LBJ. And history shows that no President ever saw that his friends and benefactors made more money, through government contracts, than did LBJ.
Some biographers have pointed out that, not only did LBJ deal with and have as close friends and associates, some sleazy, corrupted individuals, but that there is also the possibility that he, himself, was involved in another political murder, much earlier in his career.
