[4] Additionally, she leads GMF's signature Congress-Bundestag parliamentarian exchanges and the Technology Transatlantic Congressional Study Tour, which focuses on global digital and privacy issues.

In this post, Lewis stimulated the formation of relations between the Department of State, domestic subnational leaders, and their international counterparts.

[5] As part of Secretary Hillary Clinton's 21st Century Statecraft, Lewis' office was responsible for serving the global needs of U.S. intergovernmental officials and the entities they represent.

She was the principal staff coordinator for the White House Task Forces on the 1996 Atlanta Olympic, Paralympics Games and the 1994 FIFA World Cup of Soccer.

"[11] On September 13, 2021, President Joe Biden nominated Lewis to be the next director of the Export-Import Bank of the United States.

In May, 2023 Chair Lewis led a vote to approve nearly $100 million in Export-Import Bank financing for an oil refinery expansion project in Indonesia,[16] which environmental groups criticize as directly violating President Biden’s commitments to end overseas fossil fuel financing, including at the 2021 UN Climate Change Conference.

[17] The approval was also repudiated by the White House National Security Council, which stated the “[t]he administration stands by its commitment to end new direct public support for the international unabated fossil fuel energy sector...Ex-Im made an independent decision to approve the loan under its authorities and its decision does not reflect administration policy.
