We already knew that at the time during these impeachment hearings, from her opening statement:

The Obama administration did not ask me to help the Clinton campaign or harm the Trump campaign, nor would I have taken any such steps if they had. Partisanship of this type is not compatible with the role of a career Foreign Service Officer.

I have never met Hunter Biden, nor have I had any direct or indirect conversations with him. And although I have met former Vice President Biden several times over the course of our many years in government, neither he nor the previous Administration ever raised the issue of either Burisma or Hunter Biden with me.

That last part should have implicated her in lying to congress. We know she was briefed by the Obama administration on what was going on with Hunter and Burisma.
