Democrats won majorities in the Senate and House in the Nov. 3 midterm elections, according to The Associated Press. The next Congress convenes in January. Republican Donald Trump remains president.

NPR also reported Democratic control of Congress, citing its analysis of AP race calls. These are reported election outcomes, rather than certified final results. Some contests remain unresolved, so the eventual size of each majority is still being determined.

The Senate gains included seven seats previously held by Republicans: Iowa, Kansas, Maine, North Carolina, Ohio, South Carolina and Texas, NPR reported. The news agency identified winners including James Talarico in Texas, Sherrod Brown in Ohio, Josh Turek in Iowa and Troy Jackson in Maine. Democrats also retained Georgia, where Jon Ossoff won reelection.

NPR reported that Democrats had announced plans for investigations concerning administration actions and the business interests of Trump and his family.

Control of Congress will not remove the president's veto power. Trump has said he would block Democratic legislation, while also leaving open the possibility of agreements.

AP reported that Alaska and Mississippi still had unresolved Senate contests. In Alaska, the administration has sought to block certification if Republican Dan Sullivan loses, citing another candidate with the same name. That reported legal action does not establish that certification has been blocked.
