Should I invest right now?

We finally got 5k to invest with and were going to do a USAA portfolio, but with everything going on rn with the USA, should we go ahead and invest? A friend whose husband has invested a lot told us that he's gone ahead and pulled a lot of his investments as he feels the craziness will start to affect his stocks. Can I get some guidance on if we should continue with our plan? This would be our first time investing.
