Department of Justice alleges SpaceX not hiring non-US citizens?

From today's news feed:

"Musk’s company has filed a lawsuit against Garland after the DOJ alleged that SpaceX refused to hire people who were not U.S. citizens or green card holders.

Musks company responded:

"The lawsuit states: “SpaceX has not engaged in any practice or pattern of discriminating against anyone, including asylees or refugees. To the contrary, SpaceX wants to hire the very best candidates for every job regardless of their citizenship status, and in fact has hired hundreds of noncitizens.”

So basically the government is alleging that a private American company is hiring Americans and that is somehow bad? Please correct me if I am wrong, but if we are trying to run a successful company like Elon Musk, or run the successful government which we deserve, shouldn't we try to hire the very best? This is where Bidens government is failing the American people. Examples: 1. Trying to appoint federal judges that have traffic court experience only, 2. Trying to appoint federal judges that do not know the articles in the US constitution 3. Appointing Kamala Harris as "Border Czar" vs anyone else with even a minimum of experience in border control. 4. Selecting candidates for governmental positions based on appeasing subsets of the American population vs trying to find the most qualified individuals available.

We are America! We decide our own destiny. We do not want to be a mediocre nation. We can only be a great nation if our government is loaded with qualified and competent officials. Why do our elected officials keep appointing less than competent individuals to government positions?

Lets elect someone that wants the best for all of us Americans. Vote for me in 2024. I will not let you down.
