Now moving to college admissions in the US. Getting into Harvard is difficult, even for top performing students. With an acceptance rate of less than five percent, it takes more than perfect grades to make the cut. But how Harvard determines eligibility has come under fire, from some rejected Asian-American students, who claim the school has a bias against them. Karina Huber joins us from Boston.

Last week, the U.S. Justice Department gave a big boost to a controversial lawsuit that claims Harvard discriminates against Asian-Americans. Through a so-called 'statement of interest,' department officials said: The record evidence demonstrates that Harvard's race-based admissions process significantly disadvantages Asian-American applicants.'

At the heart of the case is the accusation that in admissions Harvard holds Asian-Americans to a higher standard and it allegedly uses personal ratings to artificially cap the number of Asian-Americans.

Swan Lee filed a similar complaint with the Department of Justice that has triggered an investigation into Harvard's admissions practices.

SWAN LEE, CO-FOUNDER ASIAN AMERICAN COALITION FOR EDUCATION "Even when Asian-American applicants have similar qualifications as students of other racial groups, Harvard would mark them down subjectively in personality ratings claiming they are not likeable or they're not having good character and stuff like that."

Harvard denies it discriminates against Asian-Americans, or any other group. Among minorities, Asian-Americans, are the most represented at Harvard accounting for 22 percent of its class of 2021. That is far above the percentage of Asians in the U.S.

KARINA HUBER HARVARD UNIVERSITY "Harvard strongly defends what it calls a holistic approach to admissions. It looks at race and many other factors beyond academics and extracurricular achievements in its goal to create a diverse student body."

Numerous studies have shown that all students benefit from different viewpoints that a diverse class provides. Some Asian-American groups, and more than 500 academics, have come out in support of Harvard's admissions practices.

JEANNIE PARK, PRESIDENT HARVARD ASIAN-AMERICAN ALUMNI ALLIANCE "Harvard in particular has a mission to produce citizens - citizen leaders as they call them who are going to lead communities of all backgrounds, races, colors. And so part of what they need to do is admit students from these different backgrounds so that they can go and lead those communities and help solve all the problems of this world."

KARINA HUBER HARVARD UNIVERSITY "The lawsuit against Harvard was filed by an anti-affirmative action group called Students for Fair Admissions that previously filed suits in support of white students against other U.S. colleges. To date it has failed to win any of its claims. The U.S. Supreme Court has ruled numerous times that the consideration of race in admissions is legal, but racial quotas are unconstitutional. The case is expected to go to trial in October and most believe it is headed for the U.S. Supreme Court. The court - and Harvard - have defended affirmative action based on race. That could change if U.S. President Donald's Trump's Supreme Court nominee, Brett Kavanaugh, is confirmed by the Senate. Under President George W. Bush, Kavanaugh organized White House opposition to affirmative action at the University of Michigan. Karina Huber CGTN Boston."
