Ryan announced Thursday he would withdraw from the Democratic contest after failing to gain traction in the crowded field seeking to challenge Trump in next year's general election.
Only 1 percent of Democratic and Democratic-leaning registered voters said they would be most likely to back Ryan as the party's nominee, according to a CNN / SSRS poll released Wednesday. A Quinnipiac University poll released Thursday showed him with less than 1 percent support.
Ryan had last appeared alongside fellow candidates at the debate stage in July, and did not meet the necessary thresholds to take part in the September and October forums.
In an earlier post Friday morning, Trump also targeted former Democratic presidential contender Eric Swalwell, a California congressman who ended his campaign in July.
“Another big dropout of the Presidential race was, along with 0% Tim Ryan, 0% @RepSwalwell. Such talk and bravado from both, and nothing to show, ”Trump tweeted . “They stood for nothing, and the voters didn't stand by them. Obnoxious and Greedy Politicians Never Make It in the End! ”
Swalwell has remained a vocal critic of the president in his capacity as a member of the House Intelligence Committee, one of the three congressional panels leading House Democrats' impeachment inquiry.
