Retired U.S. Army Lt. Gen. Keith Dayton told the Senate Foreign Relations Committee that it would be "reasonable" to report any attempts by the Trump administration or others to solicit foreign interference into the 2020 election.
Dayton was pressed on whether he would report any information to the Senate Foreign Relations Committee, too.
The case centered on Trump asking the newly elected president of Ukraine to look into dealings connected to Joe Biden's family -- specifically, the decision to back off an investigation tied to a company where his son Hunter worked -- with a White House meeting and millions in security assistance hanging in the balance.
The last ambassador to Ukraine, Marie Yovanovitch, testified during the House impeachment hearings that Trump recalled her from her post in May following a smear campaign lead by Guiliani telling people she was not supportive of the president.
Menendez asked Dayton whether Trump's decision to withhold security assistance to Ukraine was wrong.
