In the clip on the Hannity show at :48 seconds, starts out by making the case that a President cannot be impeached based on a prior case.
Levin said "I don’t know if people are aware of this, but the Vice President Collier case of 1873 set the precedent… Presidents and Vice Presidents are different (and cannot be impeached on events that occurred prior to their service as Presidents or Vice Presidents).

The problem is there never existed a “Vice President Collier”. In 1873 there was however a Vice President Colfax. In September 1872, during the presidential campaign, Colfax’s reputation was marred by an article which indicated that he was involved in the Crédit Mobilier scandal, a big deal at the time. Colfax was one of several Representatives and Senators (mostly Republicans), who were offered (and possibly took) bribes of cash and discounted shares in the [Union Pacific Railroad, Crédit Mobilier subsidiary] in 1868 from Congressman Oakes Ames. Henry Wilson was among those accused, but after initially denying a connection, he provided a complicated explanation to a Senate investigating committee, which involved his wife having purchased shares with her own money, and then later canceling the transaction over concerns about its propriety. Wilson’s reputation for integrity was somewhat dampened, but not enough to prevent him from becoming vice president.
Colfax also initially denied involvement to the press, but a Congressional investigation in January 1873 revealed that in 1868 Colfax had taken a $1,200 gift check for 20 shares of Crédit Mobilier stock from Ames. Colfax had deposited $1,200 in his bank account at the same time Ames recorded that he had paid Colfax $1,200. Throughout the investigation and after leaving office Colfax denied having taken Ames’s $1,200 check. At the end of the investigation in February 1873, Colfax was not censured or forced to resign, mainly because the incident took place during his tenure as Congressman, and because he was scheduled to leave office the following month.
In addition to Colfax’s involvement in the Crédit Mobilier scandal, the investigation revealed the more damaging accusation that Colfax had received a $4,000 gift also in 1868 from a contractor who supplied envelopes to the federal government while Colfax was chairman of the Committee on Post Offices and Post Roads, and so had influence in the awarding of such contracts.
His political career ruined, Colfax left office under a cloud at the end of his term in March, and never ran for office again. I think Mr. Levin must keep in mind the following…it wasn’t just because he took bribes at a time when he wasn’t in the office of the Vice President that he wasn’t impeached, it was that fact PLUS the fact he was ending his career the following month. And since impeachment is NOT a legal process but rather a political one, precedents are not really set by things like this. Having said that, I believe Trump is a good man and will survive the accusations against him because they aren’t true. But without a doubt, Mr. Levin should do his homework, at least enough to get the man’s name correct.
