It's not clear why these choices in phraseology constitute bias when Obama's 2015 budget featured a deficit of 2.45% of GDP[0] while Trump's 2018 budget featured a deficit of 3.8% of GDP[1].
Factually speaking, Trump did blow up the deficit, and failing to report that, instead of reporting it, would be indicative of bias.
Budgets requested by Republican vs Democratic administrations are different as the parties have different spending and taxation priorities. Reporting budgets without acknowledging that the parties are spending/borrowing/taxing in different areas would be a lie.
Printing news stories that make Republicans look bad is not indicative of bias if those stories are, as is usually the case, factually true. The solution to this problem is not to complain about media bias but rather for the Republican party to do fewer things that look bad.
