How many times has Biden told this lie?

Yes, his desecration work is well known. Why doesn’t the media do their job? Never mind, I hear the are way harder on him than they were on Trump. Biden has a long history of racism.

In the mid-1970s, Biden was one of the Senate's strongest opponents of race-integration busing. His Delaware constituents strongly opposed it, and such opposition nationwide later led his party to mostly abandon school integration policies.[109] In his first Senate campaign, Biden had expressed support for busing to remedy de jure segregation, as in the South, but opposed its use to remedy de facto segregation arising from racial patterns of neighborhood residency, as in Delaware; he opposed a proposed constitutional amendment banning busing entirely.[110]
In May 1974, Biden voted to table a proposal containing anti-busing and anti-desegregation clauses but later voted for a modified version containing a qualification that it was not intended to weaken the judiciary's power to enforce the 5th Amendment and 14th Amendment.[111] In 1975, he supported a proposal that would have prevented the Department of Health, Education, and Welfare from cutting federal funds to districts that refused to integrate;[112] he said busing was a "bankrupt idea [violating] the cardinal rule of common sense" and that his opposition would make it easier for other liberals to follow suit.[93] At the same time he supported initiatives on housing, job opportunities and voting rights.[111] Biden supported a measure[when?] forbidding the use of federal funds for transporting students beyond the school closest to them. In 1977, he co-sponsored an amendment closing loopholes in that measure, which President Carter signed into law in 1978.[113]
