Democrats in Presidential Debate Spar Over Foreign Policy, Climate VOA News The impeachment inquiry into allegations President Donald Trump sought to pressure Ukraine was the dominant focus Wednesday in Washington and the first topic on the agenda Wednesday night as Democrats competing to be the party's nominee in the 2020 election squared off in their latest debate in Atlanta. Those on the stage stood united in their support for the impeachment probe and their opposition to the president they each hope will be their opponent when voters across the country go to the polls a year from now. That spirit marked much of the debate, with candidates spending less time than in previous debates going after each other while highlighting the policy positions on which they largely agree. Senator Bernie Sanders called Trump perhaps the most corrupt president in modern U.S. history, but cautioned against making opposition to Trump the sole focus in the push to defeat the president at the polls. He pointed to economic challenges faced by those who lack health insurance or housing, and the "existential crisis" of climate change as he said the government can take on both of those and investigating Trump.
