Discrimination against black congressmen?

Is the fact that black congressmen are being charged with ethical violations evidence of discrimination or something else? The black officials think that the disproportionate rate that they are being charge evidence of discrimination. But they need a lot more evidence than just saying that there are differential rates that they are charged, such as the underlying rate that the black and other congressmen really do commit ethical violations. From The Atlantic:

. . . "I think," Cleaver said, "the facts speak for themselves."

The facts say this: African-Americans make up 10 percent of the House, but as of the end of February, five of the sitting six named lawmakers under review by the House Ethics Committee are black. The pattern isn't new. At one point in late 2009, seven lawmakers were known to be involved in formal House ethics inquiries; all were members of the Congressional Black Caucus. An eighth caucus member, Rep. Jesse Jackson Jr. of Illinois, had also been under investigation, but his probe was halted temporarily while the Justice Department undertook an inquiry of its own.

All told, about one-third of sitting black lawmakers have been named in an ethics probe during their careers, according to a National Journal review.

Only two members of Congress have been formally charged with ethics violations in recent years and have faced the specter of public trials -- Reps. Charles Rangel of New York (censured) and Maxine Waters of California (investigation ongoing). Both are black. There are no African-Americans in the Senate. Remember the most recent black senator, Roland Burris of Illinois? Reprimanded by the Senate Ethics Committee in 2009.

Those are the facts, as Cleaver said. The question is why so many African-American members have been in the ethics spotlight.

In interviews with more than a dozen members of the CBC, an unsettling thread emerges: They feel targeted. . . .
