Trump Sent Lethal Aid to Ukraine Despite Corruption Cases Outstanding But Obama Sent Pillows so Why Not Impeached?

Translate:

President Obama sent pillows and blankets for Ukraine’s defense against the Russian invasion in 2013 and 2014 (after Obama had told the Russian Medvedev on the hot mic that he would be more flexible after the 2012 presidential election), so why didn’t he (Obama) get impeached considering president Trump has granted much lethal aid to Ukraine even though they haven’t prosecuted much corruption?
