Weber chose not to run for reelection in 1992 and retired from Congress following the House banking scandal, in which he was implicated for writing 125 bad checks worth nearly $48,000.

He was a commentator on NPR the following year about developments in Congress after the Republicans took control of the House, providing commentary on the "revolution" he had helped create.

[10] Weber is chairman of the National Endowment for Democracy, a private, nonprofit organization designed to strengthen democratic institutions around the world through nongovernmental efforts.

[16] On August 17, 2016, the Associated Press reported that Mercury Public Affairs LLC, which Weber heads, had received $1.02 million from Paul Manafort's European Centre for a Modern Ukraine to lobby Congress to support pro-Russia Viktor Yanukovych during the Autumn 2012 Ukrainian elections and to block the release from prison of Yanukovich's rival, Yulia Tymoshenko.

[25] Files between Mercury and the Manafort and Gates firms connected to Yanukovich and his Party of Regions were subpoenaed by the Mueller special counsel investigation.

[26] In July 2018, New York prosecutors were referred by Mueller to investigate any wrongdoing by Weber and Mercury Public Affairs LLC.

[27] The United States Department of Justice dropped the probe of Weber and Mercury Public Affairs LLC in September 2019.
