Honored to join @SenatorHagerty, @USTreasury Assistant Secretary Chris Pilkerton, @VanderbiltU Chancellor Daniel Diermeier, leaders from @Bridgestone and @NissanUSA and partners across Tennessee for a roundtable on foreign direct investment. 🤝
As we continue to strengthen investment security while also facilitating investment from trusted allies and partners, the importance of FDI to Tennessee's manufacturing base, workforce, supply chains and economic growth is incredibly important, and I was honored and grateful to take part in such an important discussion.
